I think that's why they choose these highly emotional funerals. They are in the business of suing (daughter is a lawyer) anyone who "infringes on their right" to peacefully protest. Plus I think, being Leftists, they hope to push their repugnant behavior to the point that some will call to limit free speech.
Well, if they ever succeed in starting a riot, can we at least nail the Phelps shakedown artists for incitement?
