Telika: Do, by not treating these as isolated cases, but as a systematic. Check the disproportions.
Brasas: Agreed. And how about questions of correlation vs causation?
Certain facts about our culture are observable and undisputable, but are they wrong?
That is now subjective. You can objectively show some "invisible" (often because "too visible", too "elephant in the room") elements that illustrate discrimination, double standards, asymetrical role attributions, etc. You can then analyse how these elements define and reproduce a norm, that is how worldviews and representations are shaped by our environment and its echoing (implicit, explicit) messages. That is, how our models, norms, values, are illustrated in our discourses (including mainstream fictions, myths, etc), and how we are being "educated" by them in return. This is highly complex, because such are our societies (we are exposed to very different discourses, from varied sources, to vayring degrees depending on our specific subcultures, plus there is the individual agency and criticism, etc).
And then only, there is the question of moral judgement. What we do of the results, and do we take them as a description of a legitimate state of affairs, or do we take them as the denunciation of an inacceptable situation. This is subjective.
Both are somewhat interdependant. If you want to denounce a situation, you need to be able to describe it and show elements that your opponents would deny. And reciprocally, many researches, many raised questions, are triggered by a "problem" that warrant the investigation, wherever the investigation leads to.
In the case of gender relations, you have "gender studies" on the investigative level, and "feminist militantism" at the political level. As gender studies tend to illustrate, indeed, issues of implicit domination, its results are widely used by feminism. It has also often originated in feminist questionning, triggers that have hinted at an issue to investigate - for instance the very male-centered approach of History, or discrepancies between official discourses of fairness/equality and the repeated experience of women in the workplace (harrasment, carrier limitations), in tribunals (rape recognition), etc. Still, I do hink that both processes must be dissociated. For instance, I dislike the notion of "feminist anthropology" which sometimes replaces "gender studies". Feminism if what we do of the results, while anthropology is, in my opinion, the assesment of facts "as if it didn't matter". I think that a researcher in gender studies should forget, on the field, that he is politically "feminist". He should describe situations as they are, as if they were okay - that is, when he demonstrates an asymetry of power, describing it as if this asymetry held no ("good/bad") objective moral value, but simply exists. The political debate is, then, on whether this should be allowed to continue or not, and that's where feminism steps in.
So, this is how I split the issue of "is it wrong". I think that masculine domination is wrong (as well as other stuff), but I don't think this should show, or be the point, in an anthropological report. Same for migration issues, corruption, or whatever situation an anthropology is brought to describe. The scientific report, itself, should not be the disputed element, during the political confrontation. All parties should be ready to accept its data. Ideally. And disagree only on what to make of it.
At least that's the distinction I'd advocate. Realities are a bit more complicated of course, but no public debate will ever progress if we give up on this effort of dissociation.
