I loved the show when David Tennant was the Doctor but immediately stopped watching when he was replaced. I tried a few times afterwards but the newer doctors never felt right. Maybe a female Doctor can fill in that hole.

No, these things exist but I don't see a lot of them. My guess is that you see more of those things as extremist as I do.

As you can see, it strictly depends on how people perceive "male" and "female". It's not important at all to those who see it as a difference of body (and difference of education). It is very, very fundamentally important to those who see it as a difference of "essence" (some inherent trait that determine personalities, and will always make women be-that-way and men be-this-way - no matter education, culture, individuality, personal experience, etc).

So for the latter, a same "person" (like The Doctor) could never have a body of different sexes. I suppose that they will always interpet behaviours through this filter, even if it's scripted the same way (for instance, a male doctor screaming "run!" would be dispaying manly rationality, while a woman screaming "run!" would be showing womanly hysteria or weakness ; a male doctor showing compassion would show manly philosophical benevolence, a woman doing it would be maternal or expectedly sensitive, etc). And they will always attribute such difference of interpretation to an objective "character change", independant from their look (the same way Coke "tastes differently" to us whether it's tinted red or blue).

Or, if a behaviour cannot be reinterpreted this way (if it gets too blatantly "the same character"), I suppose they will have to go "This is unrealistic, a real man/woman would never do or say this".

But yeah, it's all about the ability to imagine that a same entity could "pilot" (or "live in", or "be reincarnated in") a male or a female body. Since the beginning of the series, our societies have progressively evolved away from the idea that "men souls" and "women souls" are pre-programmed by nature to feel and act certain ways (wash dishes, prefer pink or blue, dominate or submit, follow reason or intuition, etc). It's getting reflected in TV series nowadays. But it's still shocking to some people, depending on their deepest beliefs.

I mean, "opinions".

Oh, not that SJW crap again! Srsly, there is nothing "progressive" in change of morality.

That's right! You tell em LootHunter!

welcome to 2017, where your type of sexual organ is a "social commentary"

p.s.: (on related topic) ghostbusters 2016 bombed because the movie itself sucked.

Seeing gender as a social construct more than a biological condition is a "change of morality"? Wow. Your Bible must not be far from your PC.

Culture (home culture, school culture, national culture) has a lot to do with what we perceive to be a "Man" or a "Woman". Those genders implies roles and functions that, as we know today, can be interchangeable. The thing with gender theory is not to erase the "Man" or the "Woman". It's mainly to allow everybody to freely embody the role or function without being stigmatised as acting "like a man" or "like a woman".

Hence, a woman as The Doctor can incarnate the attributes of the role (quick-witted, clumsy, strong-willed) while bringing a special twist from the actress' persona. It's a new blend and it's a bloody good idea to try. Iconic characters should wear different masks.

On that point I share your confusion. Although, there is strong evidence of children, mainly approaching puberty, who knows in advance that they are a "boy" or a "girl". If these individuals' suffering is strong enough to convince them to go through hormones therapy and genital surgery, I'm betting that they need it. If you ever took a look at the procedure to transform a penis into a vagina, I bet that you would be pretty fine with your willy.

That being said, I tend to believe that mass media and social media bring a strong spotlight on a minority in our society. It's trending. Thus, it leads us to believe that there is a person ready to change sex at every corner of every street. When we are in fact seeing a minority.

The thing with "gender theory" is that it's just a theory. Made by people with certain views and morality code. If you claim that those views and morality are superior (more just and progressive) than views and morality of others, it's you, who is blinded by religious zeal, not me.
Noone is allowed to freely embody the role or fucntion under "social justice" and "political correctness". Today people are stigmatised as acting "racist", "sexist" and "homophobic".
Personally, I don't care if new Doctor will be a man or a woman or even a pony (can next Doctor regenerate into a pony? Ple-e-ase!). What really bothers me are regular "social justice" messages.

Like in penultimate episode, when Bill basically tells The Doctor that Time Lords are sexist, because they are called Time Lords and he basically agrees with her (instead of arguing that being evolved and progressive means that they don't need to check and erase every single man/woman reference in their language).

News just in, Dr Who will now be played by a pre-op transsexual and the name changed to Dr WTF.

I could not really understand what people are really discussing in this topic. However, I felt like sharing my own opinions about gender or mainly gender equality.

First, (in my opinion) male and female are not equal. They both have serious physical and metal differences. That's why we have different leagues for women and men in sports and I will always be against anyone who suggests they should be combined.

While I was working at private sector, I never expected a pregnant woman or a woman with young child to work as long as the rest of us at project seasons. As they left early, the rest of the crew (mostly men) joked about making children. At least I think they were joking :)

However, gender was never a criteria for me when I hired or fired someone. Can they get the job done? Welcome. They can't? Goodbye. Yes, in IT business most people are male but my best were mostly women.
------------------------

I want to add a few words about sports. I have been playing an online manager game called managerzone for over a decade. There is football and there is hockey and there is no female team section. So I suggested "female" players, female names to be added into the game and it was well received. Of course, that addition would only be esthetic, no difference between male and female players.

Can we do that in real life? I think not. Because although online (virtual) players are not real, real players are. If we would combine female and male football (soccer) leagues, females would not be able to find enough chance. Sure, one or two women in a decade might turn out to be good enough to play in the top leagues but in general it would be a major let down for female players. Same in basketball, volleyball and tennis. So my vote is for giving every gender equal chance in sports.

That's not the case in army tho. We have some excellent female soldiers, pilots etc. I had the great pleasure to work alongside some of them.

In conclusion, I don't expect women or men to act equal but do not differentiate them solely based on their gender.

Evolution is also "just a theory", at least in your case.

Ahh, the ''everything is just a theory'' fallacy. Where you accept the theory out of the openness of your mind and refrain from being rude and asking for substantiation.

The thing with the "theory of gravity" is that it's just a theory. Made by people with certain views and a certain world view. If you claim that those views and world view are superior (more accurate) than view and world vew of others, it's you, who is blinded by religious zeal, not me.

On a more serious note, the problem with this part of your post is that it misrepresents what a theory is.
