You have to allow some debate to take place, and while i agree the forum does have a few members who's argument methods leave a little to be desired, i don't think the debates are at fault.
I'm aware the threads are very closley watched and, I, personally watch them quite close out of interest. Its very rare things get un civil, humour is productive if used in context and later explained if its misunderstood.
Classic example is when me and 2fast4u lock horns.. check old threads, you see any anger towards each other? No!! Its true of most people here.
The fact that most threads are becoming polotical shows that a lot of the board wants to talk about it. It does not stop other threads, and i truley believe that threads aren't allowed to go out of hand.
The name of an old shakespeare play comes to mind.. "Much ado about nothing"
