These "norms" are generalized and not always applicable to real life. If I disapprove of you yelling "Fire!" in a crowded theater, should I also have to defend your right to yell "Fire!" in a crowded theater? We "erode freedom of speech" when it hurts people.
This is not about "weird people with quirky ideas". This is about people who use speech to abuse, cause harm, intimidate, harass, or inspire others to commit such abuses. This cannot be tolerated in a society that wants the right to "Life, liberty, and the pursuit of happiness."
One can always find a non-abusive way to present an idea. But when they cross the line into a form of abuse or violence, they should be stopped.
