I have a lot of interest in protected classes (gays, blacks, jews, etc) and I'm wondering how they emerge. Is there a common event that raises a certain group to protected status. Or is it a common trait? How do these groups go from being underdogs that are routinely "abused" to protected status where they become virtually untouchable? Your thoughts? And please, can you give me 2 or 3 pages of discussion before we make this about the rep system or speculation of various posters hygiene habits, etc? I'd really appreciate it because I'm trying to learn.
