You know, there are probably at least several websites catering to almost every special interest imaginable, even the most arcane ones, all filled with people who love to talk about that subject. That's why they belong to those sites.
My special interests are music, cycling, and fishing. I belong to at least 3 websites for each. People there care more about your sharing their interest, than your personality. Look for ones that have hands-on moderators, who don't tolerate personal attacks.
