There may be generous and plentiful libertarians
A while back I spent six months living with a thieving, drug dealing black guy, so I guess my opinion that black people are thieves and drug dealers isn't entirely false.
Anyway, on topic, I don't really have any deal-breakers, at least not in terms of interests tastes. However, like queen mother of the peach pie, I do need anyone I date to be roughly as intelligent as I am, or more so. And probably for them not to take me too seriously or respect my opinion, as I seem to argue a lot for the sake of it, so I spout a lot of crap.
I don't think it's hating on upper-middle class people to have a problem with an absolute prerequisite of having been a world traveler. Maybe you can say you gravitate toward "worldly" people, which could possibly include open-minded, intelligent poor people who haven't yet found the means to indulge their love of exploring other places. Why would you as a rule exclude someone who is well-read about the world and all its most fascinating destinations just because they haven't had the experience yet? Maybe the people who posted that wouldn't necessarily exclude them, but merely didn't word it more sensitively.
I'm sorry if you feel like I'm ragging on you. It just seems like a HUGE brush to tar someone with. Maybe I just don't get a certain subcultural significance of those particular films, but to me, that's like saying "I'd never date anyone who likes grilled cheese sandwiches."
And for Sixties Liberal, regarding bookshelf scanning - to me, it's not so much seeing one particular book on someone's shelf, but the overall impression. Mein Kampf might raise eyebrows, but it wouldn't be a dealbreaker. But if half their books were about Nazism, especially if many of those books seemed to be on the wrong side of that particular debate, yes, that would be a big deal. Though I would probably ask about it before just fleeing their apartment.
On the other hand, if I saw The Protocols Of The Elders Of Zion up there, I would not hesitate to write that person off. Unless I already had a really good reason to think they only had it for 'academic' purposes.
