Solely based on their sexuality? Of course not.... then again i did't grow up any kind of culture that bore ill-will to people based on their sex or sexuality. I do feel uncomfortable around gay/bisexual people if their personality rubs me the wrong way. For instance, i used to work with a person who would, quite crudely but i lack other terms, be called rather "fruity?". A very, feminized young man who never did me any harm yet the way he moved, talked and behaved in general sort of crossed wires in my brain saying "watch out, he's not normal!". But, and goes to show that the whole thing about books and covers is true, that feeling never passed, upon explaining why i was less "sociable" with him then my other colleague's he simply understood, accepted it and we went on from their. The 'feeling' subsided slightly over time mind you, but funnily enough plenty of straight men, and woman, give me the same feeling. When their behavior is just to out of place for me to accept.
Any-hooooow, my 2 cents.
Come one, come all i' say. Just don't get drunk, kiss me in the middle of a freaking party and then go "oops... tee-hee"..... .... yeah........ that happened.
