Free speech refers to the amendment stating that the government won't make laws restricting speech.
It has NOTHING to do with what and who is allowed on a message board.
This board could use some serious cleaning, IMO.
The mods do work actually, I myself had a few unrelated post removed. The difference though is the mods do not go egotripping making threats like on some other boards. This is a good thing.
It is up to the users not to engage or encourage shitstorms in the first place. If you are looking for nanny mods there are plenty of boards to choose from. The fact that moderation goes unnoticed just shows some maturity.
