I can't even grasp the idea of someone's sexuality being offensive. I'll guess the OP is asking about the depiction of women in TW3.
I find it pretty accurate to the setting and the books. Peasants look like peasants, there are old people -including women- which is a relief, prostitutes in trade are cleary recognizable as such, and sorceresses play in their own league aesthetics-wise. Yennefer's design, for instance, is very classy and true to the source material. Aside from that, female characters have personal stories and motivations, and don't exist as plot device to be rescued or whatever, so... The game pretty much stands above 90% of titles in this regard.
As a woman myself, I feel tired of all this pseudo-feminist bullshit. I appreciate when a custom character RPG lets me play as a woman, and I am able of acknowledge that not every company is willing to put resources for women to play as female, so kudos to them. I can't stand bethesda, so I was left with some bioware and obsidian games and not much more. [I'm still mad about bioware not putting female animations on fem-Shepard ME2's cutscenes and having my character walk like a cowboy and sit with her legs spread like she had balls.] Anyway, we went from games for boys only, to raising shitstorms when someone puts a whore showing her tits in a game, because that hasn't ever happened... right. Neither people taking advantage of their bodies in order to achieve goals. :mellow:
I'd rather have settings with believable and coherent cultures than some sort of disney world when everything caters to american political correctness, and thus everything feels fake and shallow (sadly, looking at you, DAI).
