Freedom of speech. Unless in someone elses private home. Then they can shut you up and kick you out

Telling people things they do not want to hear is not just related to the question of "How free is free enough?" but it is also one of the answers to the question "Why are there more than one person?"

The only speech that requires protection is unpopular speech. In addition, it seems the case that whatever one says, someone somewhere is going to be upset by it.

In a society with Constitutionally protected freedom of speech, yes, you have a right to say things even if others don't want to hear it. That doesn't mean you can't be held responsibile. If you commit libel or slander, or treason, or cause a public health disaster by falsely yelling fire in a crowded theatre, then you can be brought to justice for what you have said. Ultimately, however, you have the right first and foremost to say it, regardless.

That includes on debate websites. I've been on three debate websites stretching back about a decade and I have always defended the rights of anyone to say anything they want. Sometimes moderators or site owners intervene, but that's just a living example of being held accountable for what you've said.

You have the right to say whatever you want. It does not however mean that there won't or can't be repercussions for it. Standing in a crowd and saying you're going to shoot the President, for example, is going to bring about some pretty severe retaliation.

Like wise if you tell a pregnant woman she looks fat, you'll probably get shamed or slapped.
