Interesting case of Snyder vs Westboro Baptist Church.
As far as I understand it, the Supreme Court upheld Westboro Baptist Church's rights in this case.
They voted 8-1 in favour. The one dissenting judge was reported as follows
"Snyder's lone backer, Justice Samuel Alito, wrote a passionate dissent that accuses his colleagues of being plain mean. "Respondents' outrageous conduct caused petitioner great injury, and the Court now compounds that injury by depriving petitioner of a judgment that acknowledges the wrong he suffered," Alito wrote. He seems to be asking them, How can you sleep at night? "In order to have a society in which public issues can be openly and vigorously debated, it is not necessary to allow the brutalization of innocent victims like petitioner," wrote Alito. "I therefore respectfully dissent." Perhaps another adverb is more fitting: angrily."

That is how the law works. One day the majority may be the other way and that may set a precedent.
