I'm pretty sure the only reason people even become vegans is because they have so much hate bottled up inside.
As for the music thing, a girl that liked the music I like would be fucking awesome... I don't really see how it's an odd preference to have. I get really into the music that I listen to, as I'm sure a lot of people do... And if you can't listen to some Devendra Banhart or some Vanderslice every once and in a while, I just don't know how it would work. I mean, I understand that most non-pop music is an acquired taste, but, if you aren't even willing to get attached it'd be a big turn off. See, basically, what it would come down to is, are you into even the same genre of music?
I dunno, whatever... This is actually probably a huge look into why I don't get laid.
EDIT: Next time I type once and a while there will be a lynchin.
