Answer: "Marriage defenders" who picket funerals of slain soldiers and movie stars because "God hates fags."
I can't decide if Phelps and Co. are mentally unwell or if they picket funerals just to get attention for themselves. Perhaps both.
Whatever the case, the only positive to come from this disgusting display of hatred and disrespect is that it helps turn the masses off from the anti-gay movement.
Rest in peace, Heath.
