>Case in point: legal or not, people cancelling speeches and people, shutting down legal speech, do NOT stand for freedom of speech.
Except that heckling and shouting down a speaker is speech too. And thus your argument is incoherent: do you want to restrict speech that impedes other's freedom of speech? If no, then the hecklers must be given free rein; if yes, then the case can be made to restrict racists' freedom of speech as they try to restrict some other people's freedoms, including the latter's freedom of speech.
