Hate speech isn't free speech. If your speech is a call for the destruction of basic freedoms and rights for other people (the right to life, the right to free association, the right to bodily autonomy, the right to self-expresson, the right to free speech, etc), then you have invalidated your right to free speech itself.
Can't tolerate intolerance. As soon as you exercise your rights to infringe upon mine I'm entitled to use any means within measure to defend them.
