I'm a little confused, too, Boomer.
Suppose I started a thread entitled "homosexuality." And suppose that (unlike littlek) I expressly stated that I wanted to confine the posters in my thread to those who had an extreme aversion to homosexuality and whose purpose was to ridicule, demean, insult and discredit homosexuals in any way they could think of.
Now suppose a few posts in that vein were made.
How long would it be, ya think, before "creeps" came in and expressed a contrary view?
And if I told them they were not welcome in my thread, what do you think their response would be? Do you think they would immediately apologize and graciously bow out? For some reason, I kinda doubt that's what would happen, ya know?
