The Westboro Baptist Church is notoriously litigious -- anyone who pushes back against their vile bullshit gets sued to death.

Phelps himself was an attorney (later disbarred), and five of his 13 children are or were apparently lawyers, as they were reportedly sanctioned by the Federal Court in their district along with their father. Something like 40 of the WBC parishioners are lawyers who volunteer their time to use the civil justice systems to harass the enemies of the church.

Ridicule of the sort practiced by the Comic-Con geeks really is the best way to deal with these fools. Well done.
