Are there good ones and bad ones? Stereotypes, I mean.
I'm at the age where the "daddy" stereotype has kicked in and I am either shunned by gay men who seek younger men, or sought after because I have white hair and a beard that matches. The point is that stereotypes are prejudicial (in the real sense of pre-judging) one way or the other, either of which is somehow diminishing to the stereotyped person. I'd rather be known for who I am under the white hair and inside the head that grows it.
On the other hand, I deplore this trend among all of society that we can't laugh at ourselves anymore. Where to draw the line, huh?
