It's marketing. Usually free speech absolutists just want to be able to say bigoted things. Often, they're simply racist.

People are very volatile and polarized because of their social media's marketing. GOP marketing is insane. They're marketed as fiscally responsible, good for the economy, conservative, pro free speech, pro liberty, capitalist, and recently anti-war. And somehow people believe that despite reality. I can't grasp how anyone could ever support someone so awful as Trump. The man is a pathetic spoiled rotten bully in clown face who can barely string together a coherent sentence. Not to mention all the (sex) crime.
