No one here is arguing for this guy to be locked up. They are arguing that this guy is a douche, and that everyone should think that he’s a douche. Big difference.
While the first amendment let’s you say almost whatever you want with a few caveats, it only protects you from the government. Private citizens, private organizations, and private businesses have all the rights in the world to never interact with this guy in a positive way again based on what he said if they want. We can judge his speech harshly. We can denounce him and convince others to denounce him. We could petition Twitter and Facebook to deplatform him right now with no real constitutional recourse - and before you tell me I’m wrong, they already did it with Trump. Twitter/Facebook could choose to do that on their own! I can even openly advocate for other free citizens to legally boycott this guy based on his beliefs. I can tell everyone else that this guy is a shitty dude, if I want. I can try to convince others of the same. As long as I don’t lie about facts, I am absolutely protected, and you should embrace that no matter how much you dislike it.
It’s a common misconception that the first amendment gives you any more protection for yourself than freedom from gov persecution. It’s not freedom from societal judgment. Not even an iota.
Also, arguing tolerance of all free speech could be what brings us back to the middle is a ridiculous over generalization. Would you have been the one arguing for tolerance of the American Nazi Party’s platform in 1946? Sure, the gov shouldn’t do anything if it’s not criminal. But private society choosing to harshly judge someone for being a childish douche? Sorry bout ya.
