I disagree somewhat with your analogy, as these are words people use to describe themselves with pride. They're not just outsider stereotype sthat insiders are uncomfortable with (like the stingy Jew or the athletic black guy or the Chinese math whiz).

Which one non-gender-specific word would you use to describe a fanboy, other than 'fanboy'?

Anyways, don't bring up new interesting points and then say the horse is dead and we should stop flogging it. ^^;
