Well, I don't find it obnoxious because I don't think that is true. It's not true of Baldur's Gate or Temple of Elemental Evil for example, it's not true of Dragon Age (for a more mainstream example). I'm struggling to think of ANY RPGs where males are under-represented.
I can agree insofar as I have a dislike of stereotypes, be they male or female, I just think that RPGs tend to be pretty good about this (at least the ones I play) and if anything, it is female characters who are under-represented or misrepresented due to the disproportion of male:female gamers, among... other things.
I think you have a point about 'anti-male' culture in the sense that there is a common theme in today's media (most notably tv advertisements) where the female (usually the mother in a family setting) is portrayed as wise and savvy whereas the male is a bumbling idiot used for comic relief. However, this hardly makes me sick and I feel concerned for you that you would express such strong language about it. The reason this barely bothers me is because I recognise it as merely a shift from stereotypes that negatively portrayed women, a rebalancing of cultural norms as it were, which tend to feature some backlash against the initial source of error. Namely, the appalling way in which women have been treated in the past (and present). Yes, males have their own share of societal hardships and stereotypes and so forth. We are ALL caught up in this thing called society and it has many, many issues that make it challenging for us to flourish as human beings to our full potential.
So my question to you, is WHY does this bother you? Of all the stereotypes, all the terrible issues of the world, all the sexism, racism, hatred, cruelty and so forth, why do female characters in RPGs bother you so much? If it's a family thing or something like that, please I don't mean to be rude and you don't need to answer, I know how stuff can mess us up believe me. I would simply encourage you to think about why this bothers you so strongly and try to get some perspective about this issue, as it seems to me you may have a rather distorted view of the proportion of gender stereotypes and character representation in video games.
Now, do you want to know what makes me 'sick'? The stereotypical way males are portrayed in games as hulking muscular brutes, as you yourself alluded to. You see, I find it hard to identify with/relate to the hugely muscular brute (even though I'm more than happy with my own physique) and more importantly it reminds me of the things I don't like about male behaviour and social conditioning in general society. Yet I try to keep things in perspective and not let this interfere with my ability to enjoy the game I'm playing. I recognise that it can be an unintended consequence of limited resources resulting in a single character model, however I would much prefer a variety of models to choose from, or at least leaner more realistic models. As I'm sure, many women would appreciate a variety of character models beyond the ultra-curvy one commonly available, that is, when they actually get the chance to play as their own gender as males can take for granted. However I patiently put up with this because I understand it can be a resource issue and compared to what women have to accept and all the other annoyances in gaming and life, it simply isn't that big a deal.
So all things considered I would consider yourself fortunate that Original Sin will provide you with the opportunity to at least play both the two protagonists as the gender(s) of your choice. Who knows, maybe one day on a subsequent playthrough you'll feel like giving a female character a try, perhaps as the AI-controlled protagonist to your male one. One day, looking back, you might even marvel at how it used to bother you. And if not, well, we can be grateful that at least we have the choice and opportunity to play as we like in this game.
