A practical idea... why not create a "free speech" thread where people can discuss without heavy censoring. It could be off the main page and nobody is forced to read it if he do not like it (of course not insulting people like "xyz is a idiot/stupid" and so on
Funny you should mention that. It was tried at Amigaworld.
Guess what? No one used it, because they could not receive the same attention from posting on "back pages".
In fact, creating such a place and instructing people to GO there is the fastest way to stop a flamefest.
