This is the view of someone who thinks everything revolves around him. Anonymous people are rude to him online, so "mandated speech" (opposition to which first made him famous) and other limits on expression around the world suddenly stop existing. People have had knocks on their door for far less offensive things than calling someone a "sadistic Machiavellian psychopath" - in the UK recently it was "muppet" (offline), in Germany it was "dick". It doesn't even have to be a direct insult. Satire can get you unwanted attention too. Even criticism.

If he believes what he said, then he is a sadistic Machiavellian psychopathic narcissist.
