It's kind of weird to mentally go over all of my friends and rate them in terms of how many are really 'real friends' and how many are 'just' good friends. Lets' just say i have quite a few friends and some of them have been my friends for a very long time and definitely belong under the 'real friend' banner like you described, even if a couple of them go to insane lenghts about everything in their lifes simply cause they're...well...insane.
I'll probably pick up a few more along the way, but the ones i have right now are all that i could ever ask for, both in quantity and quality.
And yeah, that add it's very unimaginative even if i would expect the sentence works for lots of teens, since many kids seem to have very few real friends these days. Still, meh...

Wonder if they considered the effect on depressed people...

Or to summarise: People are selfish

Yeah, in general that sums it up quite well unfortunately.
There are also a few instances where people get so caught up in whatever it is they're doing that they kind of loose prespective and sometimes even a part of who they are in the process.

"If only he could have used his powers for good, instead of for evil"

Well, maybe not to that degree.
I don't mean they become villains, just that they loose sight of stuff going on around them that is as important as whatever it is they're doing.
Maybe people just weren't build to live the way we're living today, and after a while that shows.

It might be due to the rapid development of our technology. It leaves a huge gap between generation when the previous one dont understand it. Also poeople tend to dislike new, unknown things until it has been proved as a good addition to our society.

Like how people will be initially scared of my divisions of depopulation killbots but will come to see them as friendly and beneficial when they realise that depleting 75% of the planets population will give them much more room to move AND reduce the strain on the planets resources.

This is what happens when pressure groups get all the rights they asked for and run out of things to campaign about. They just start driving a wedge between themselves and everyone else - exactly the kind of wedge they were originally so keen to see removed. The same thing happened to the women's rights movement. The ones that stayed on were just bitter man-haters.
This bullshit doesn't even make sense. More friends than games? I don't think I could sincerely call that many people friends, no matter how much of a socialite I aspired to become.

Well I have around 100 games... I'm not sure its even humanly possible to have that many proper friends.
Also just looking at the poster I had no idea what they where trying to get at. So they have rather solidly failed.

Inspite of the add being bullshit, it's not trying to pass the message that people should have more friends than games.
They're just trying to say that people should be nicer to each other cause making friends it's hard. The gamer/games thing is just some unispired attempt of turning the tables on the use of the expression they're lobbying against through the use of a stereotype usually related to gamers. Kind of a (very)low budget version of the 'do to others what bla bla bla' thing.

I can't see why this upsets people.
The whole idea is to make a point by throwing out brash stereotypes about other groups, one of which is gamers (which is amusing, because gamer culture in particular loves to use 'gay' and related terms as general slurs). The other two posters are about jocks and cheerleaders. These three groups are pretty common in American high schools, which, according to the site, is the target of this campaign. It wouldn't make sense to use lawyers or insurance salesmen or other negatively-stereotyped groups as examples.
It doesn't work very well, though, because they're using stereotypes of social groups to stand in for a general insult, when the manner in which "gay" tends to be used by imbeciles really has nothing to do with any stereotypes of gay people that I know of. If it does, it's pretty oblique. It's a catch-all for people who lack the wit to come up with anything more appropriate, so any specific idea behind its usage really doesn't exist.
Most likely, they tried putting "That's so cheerleader" or "That's so gamer" on the posters and realized that it had no context and no impact, so they tried to sharpen it a bit and ended up with something that made even less sense.
But I can't say that the gamer poster particularly bothers me. All it's trying to say is "how would YOU feel?" Like I said, it doesn't work very well, but that doesn't make it mean-spirited.

I get called a gaming geek all the time. Dont care, doesnt worry me. Have gay friends who are gamers, have gamer friends who tell me what I play is gay...have gay gamer friends and THEY tell me what I play is gay...then ask me when I am finished with it.

Sticks and stones....some people need to grow a thicker skin.
