PS. I still thinking its highly wrong to push your views onto a medium just for the sake of making it one more tool in the overarching scheme of things that we call life such that your views gain greater traction in society.
Well, basically we are talking sexual objectification (that's what a bikini armor is, after all). So you have three sides, those that want it for both sexes, those that don't want it at all, and those who are happy the way things are, sexual objectification of female only. There are worlds and places where it makes sense (Conan the Cimmerian, the princesses in Dragon Commander), but I havn't seen anything that make it fit for armors in previous Divinity games.
You may say it's a political agenda, but keeping things the way they are is one too (because things are doesn't mean they have to be kept that way).
