In the grandparent comment, he accuses me of lying and hypocrisy, neither of which is correct. The only thing I had accused him of is not knowing anything about the Cultural Revolution, which is obviously correct, since he had confused it with the Great Leap Forward.

Ignorance is not immoral; it's the state we all start in, after all.

So I do not agree that falsely accusing someone of lying and hypocrisy is "identically snarky as" correctly "accusing" someone of ignorance.
