Never heard of him. (Turns out I've heard of his campaigns). Wikipedia (yeah, I know, shoot me now) said "President Bush recently signed the Respect for America's Fallen Heroes Act in response to Phelps' protests at military funerals." So now he has official recognition in law
If there ever was an argument for gun control -this is it. Why? because y'all have guns yet no-one has popped him. And you call yourselves responsible? Pah. In the UK, he'd be dead by now for sure.
