>>some people get really mad when I do that, despite the humor behind it. Dunno why.<<
Simple, because they can't laugh at themselves. Which one of us hasn't taken ourselves too seriously at one time or another?
This is true.
There are times when I have to back off of a trhead because I'm way too angry about something either in thread or in teh subject.
(Like, for example, "Peace" protestors advocating violence against soldiers. I end up seeing red and babbling aphasia over it to the point of being unintelligable.)
