Amazing how many people think they should not be allowed to protest. They observed the 1000 feet rule at the funeral. Are they jerks? Of course. But if they want to hold up God Hates Fags signs etc, they are protected just as the '78 Skokie case showed and the 1988 case of Larry Flynt. If you don't like it, you have a choice. Ignore.
