There are loads of them.  You see there's this list of groups you can't  harrass and discriminate against.  If you're not on the list, you're fair game.  You'll know who is on the list by how many times they were listed as examples in this thread.  

I saw this thread despite the poster's claims to the contrary as a call to action, a trial balloon if you will, to see how many of you all are interested in CENSORING and SANCTIONING other's people's muds because of how they choose to run it.

It's a stupid thread.  I feel dirty now that I've participated on it.
