When someone very influential broadcasts the idea that people who don't like economic inequality (let's arbitrarily call them "liberals") are waiting around to kill the rich for being rich, on the surface that is deniably close to expression of a fear. But it is also preparing a public case for supposedly "pre-emptive" suppression. Which would logically come in the form of violence, given how violent these people supposedly are.
Notice how no evidence was ever presented that those who differ with pg's politics actually are presenting a violent threat, yet we are somehow discussing it as a truth anyway. This is skilled manipulation.
I never had any axe to grind with pg's work encouraging certain startups, but when he suggests that I must be deciding whether to murder rich people merely because I am not happy with the degree of economic inequality in my country, I can't help remembering the blood libel.
