“I’m going to use Congressional authority and every influence with big tech platforms to mandate immediate ban for life of every post or commenter that belittled the assassination of Charlie Kirk. I’m also going after their business licenses and permitting, their businesses will be blacklisted aggressively, they should be kicked from every school, and their drivers licenses should be revoked. I’m basically going to cancel with extreme prejudice these evil, sick animals who celebrated Charlie Kirk’s assassination.”
That’s abridgement of the First Amendment.
