Being in a crowded, darkened theater is a special circumstance, in which people are remarkably vulnerable (as the Dark Knight Rises incident painfully illustrates). Thus, shouting Fire! in such a venue could cause deaths and injuries - and thus, it makes the classic example of speech which can damage and may be censored for the good of society. Without compromise of the ability of the people to hold reasoned public discussions of religion, politics (the two subjects mentioned explicitly in the First Amendment), or anything else.
Westboro makes its publicity splash by verbally assaulting people who are at their most vulnerable. They are picking a fight, and that should be understood in court as an assault.
I agree with you on this whole heartedly. It is a slippery slope we really don’t want to go down.
And to make this even more absurd, I have a gay friend who thinks this is a great idea. Really?
