The Westboro Baptist Church is small and insignificant. It is made up of one Witchita family, and they are NOT nice people. They picket servicemember's funerals with signs claiming, "God Hates Fags," and other odious proclamations. They are viscious and vile, and I would know, since Shirley Phelps-Roper and I have tangled before.
As awful as they are, there is something comical about their craziness. And that is the most effective way of dealing with them. Comedy. Paul McCartney trolled them on twitter. It was epic, (click here to see what he did.)
The Foo Fighters Rick-Rolled them, and it was AMAZING.
Grohl and company have punked them before.
On a serious note, Westboro is toxic, and this is why one member took a runner. Pretty powerful stuff, here.
