I'm having trouble grasping the coherence of your point.

While it may be fine to believe that some speech is considered beyond the pale (and let's leave aside the forms of speech people already agree on, like yelling "FIRE!" in a crowded movie theater), the question remains, who is the arbiter, and what standards do they apply? The point is that there isn't a consistent answer to that question. And since an inconsistent answer would lead to abuse, and to the "wrong" people having their speech suppressed, the only alternative is instead to defend free speech even when objectionable, and thus argue that it shouldn't be controlled.

The whole crux is what you're saying about the "wrong" people controlling speech, and for the "wrong" reasons. There is no consistent definition for "wrong" here, not that cannot be turned around and used against you or the people you'd define as "right".

Which is why I essentially agree with your final paragraph, at least the sentiment about not being able to predict the moving lines of what is acceptable if we were to assign values of what kind of speech should and shouldn't be controlled. But since I don't agree with your first three paragraphs, I don't understand your point of view.
