Not even close to the ethical, moral, and constitutional issues involved with letting these thugs disrupt funerals all over the country, year after year. The Supreme Court has upheld "time, place, and manner" restrictions on First Amendment rights, and it shouldn't be difficult to put a stop to this. Just trying randomly selecting a funeral in your area, and standing nearby with an obscene sign in the path of entering mourners, and bellowing obscenities at the top of your lungs, and see how long before you get arrested. This "church" has long been accorded special rights that nobody else has.
That video is so sad...Those children are being brainwashed. I hope for once that somebody finally gets them out of that sicko cult.
