“ Free speech is paying to hear your favorite artist to sing about killing cops and for people to denounce the the person for saying it.”

incorrect. you are not owed money, a job, or platform for your speech. you can say it. you are not owed a living for it.

“ You can call me every racial slur in the world. That is your right.”
nope. menacing and hate speech are not protected speech. They will get your fired.

“ So yes, I have a right to pay to hear whomever I want speak and they have a right to the audience.”
Not how audiences work, bro. No one owes you an audience nor access to Milo speaking. You want to talk to him? You can. But I don’t need to give him a speaking gig so you can see him. That’s special treatment. So why you take your sensitive, fragile, snowflake priorities and fill up someone else’s notifications.
