I believe the law should be enforced, and that the legal system should be where these issues get hashed out. And that the legal system should be very suspicious of a need for censorship; they are few and far between.
My personal take is, it's very different saying "I'm against murder", and saying "that man is a murderer". We have libel laws to protect individuals from slander, and I think that's a good thing. But I don't think there should be any prohibition on talking about policy in general.
So it should be legal and tolerated for people to loudly proclaim "all white people are racist", but not put up a billboard of some white dude, and claim he is a racist, unless you're prepared to defend that allegation in court.
It still sounds, then, like you'd be okay with the example in question: a billboard saying you're mentally ill, grooming children for sexual activity, and should be executed.
Because again, that is exactly the rhetoric we're discussing: Rhetoric which says 'X is mentally ill, grooming children for sexual activity, and should be executed'.
If it's okay to say it when X is an LGBT person, or all LGBT people, then it is also okay to say it when X is you. So why try to sue for something you are okay with?
Conversely, if it is inappropriate censorship to try to moderate such messaging when X is an LGBT person, or all LGBT people, then it is also inappropriate censorship to try to moderate such messaging when X is you.
