I definitely agree that some of the choices were really... stupid. It seems to go primarily off of stereotypes. It was pretty apparent early on that the choices went from masculine to feminine, and in some cases that just made no sense. Like, I drive two cars - a four-door hatchback and a two-door hatchback. I chose "sports car," since there was no choice for economy/subcompact/hatchback/etc. But I don't think that's particularly masculine anyway, even if it was accurate. And then the fact that the most feminine choice was a f'ing minivan.... that's almost offensive, even.
Not to mention, it seems that "socially feminine" just means that you're liberal. Nearly all the social questions were political in nature. It's true that men are more likely to be conservative than women, but I don't think that's relevant to anything.
