I'll try to keep this short... I've been seeing a lot of new people since getting out of a long term relationship, and someone I know has taken issue with the people I'm seeing (and kind of made me feel like an asshole for it, hence the post). 

Kind of touchy, because it's a race thing. I'm on various dating apps and have only been selecting for the members of the one I prefer. I happen to think this is totally fine, because that's my personal preference. But maybe I've been a bit too conspicuous about it. Recently I was propositioned for a date by a guy I go to school with - I've sort of suspected he had intentions in that direction, and now that I'm single he wanted to make a move. I politely declined. And then later I got the text that prompted this post: in which he rather pointedly called me out on my "racist" dating habits, under the assumption that I'd screened him only because he is not a member of said race (partially true). Basically he succeeded in making me feel like a piece of shit. 

I asked my roommate and her boyfriend for a second opinion, and *sort* of sided with the guy in question, though they're also friends with him. So I'm here for a third. AITA?
