On the same Don Lemon video you quote, he admitted he bought it to protect freedom of speech, regardless of if it costs him money or not. Obviously, it's his over glamorised version of events.

Considering your dislike for Elon, you're intolerance of anyone with a different opinion to you is strikingly similar.
