These aren't anti-war demonstrators they are certifiable lunatics. At these funerals they yell that the soldiers are being killed because "God hates Fags" and the US supports homosexual behavior.
Just like FR has its share of lefties pretending to be Republicans but really aren't who say "I'm a life-long Republican who opposes the war and blah, blah, blah ...", I'll bet if you dig deeper you'll find out that these are lefties just pretending to be anti-homosexual agitators who are there to discredit the people they are pretending to be.
