I mean, if you're a white guy, what do you give a fuck about someone turning America into a white ethnostate? Sure, theoretically, it's morally bad, but you're not really going to be directly affected.
If you're not trans, being characterized as a groomer pedophile has no effect at all to you.
I think it's easy to take a stand in favor of free speech when speech is only speech, but that's a remarkably naive and gullible viewpoint to have. Do you think white supremacists that lynch black people don't use hate speech beforehand and talk about exterminating non-whites beforehand?
"But that's violence. That's diferent.", you might say. How do you think these people meet each other and collaborate with each other and normalize this kind of behavior? Through 'free speech'.
