Hillary vs Obama

I was at a party and the primaries came up. I mentioned to an Obama supporter that I was still undecided. His response was basically that because I was a woman, I might want to vote for Hillary. I responded that, no, it was because I preferred Hillary's domestic policies, but didn't like that she was so hawkish, and vice versa for Obama. He agreed that Hillary was indeed hawkish. Maybe I'm being overly-sensitize, but it annoyed me that he assumed that the only reason I'd want to vote for Hillary is because she is another vagina owning-American. It must be nice to be a white man.
