Isn't there another thread about this already?
If the guy wants to be a big dummy and burn copies of the Qu'ran, let him. It's (at the moment barely) a free country... If radical Muslims want to get their panties in a twist I'm sure this will just be a pittance more than they've already got brewing. And if it doesn't occur, they'll *still* have their panties in a twist over some other ....ing thing.
And yes, 9/11 is a sad anniversary, lets hope it's not forgotten, glossed over or downplayed, or worse, made a mockery of by the tin-foil hat crowd.
