I don't need to tell you about Westboro Baptist Church, but in case you live under a rock, go to Wikipedia(I won't link you to their website because it may give your computer something nasty).
All good people find WBC horrific and objectionable; at every WBC demonstration, throngs of counter-demonstrators sing "Give Peace a Chance" while waving clever signs. I know how good it feels, I've been there.
It's in our nature to fight the hateful WBC morans; their practice of "protesting" high-profile funerals in the most heinous ways demands a righteous response.
Maybe the best thing we can do is just stop paying attention to them.
