In this instance, I think freedom of speech is a concept, not a legal issue.

I don't believe adults should be censored or sent for a Time Out, or to the "Naughty Room" , because someone objects to a post or a thread. The person objecting can move on with one key stroke.

If there is no interest in a thread, it will die a natural death. If peeps are having fun with it, why not let them?
