Enjoying the protection of being able to insult people who deserve to be insulted? Unsworth's "provoking" certainly did not deserve the drunken, reckless response that Musk gave, nor later attempts to find dirt on Unsworth.
I'm insulting Elon Musk for being a rude jerk. And according to his own argument, I'm getting away with it. I mean, no one could possibly equate Elon Musk with something that noxious waste spews from, could they?
