The freedom to be a dick is exactly what liberty is all about.
Do you think freedom of speech means you're allowed to write a letter to your grandmother? No, it means you can say controversial and offensive things without fear of government retribution.
Freedom isn't a word that's supposed to make everyone happy all the time. Liberty is about having the right to be "openly racist, sexist, misogynist, transphobic, and homophobic", without fear of physical aggression.
That's not to say there aren't consequences for one's actions, but a free society isn't one that mandates everyone conform to specific belief system, it's one that allows people to believe what they want and behave as they like, as long as they don't physically hard other people.
