Guilt by association is really toxic. Please don't open this door. Epstein had a little black book with thousands of names and you're basically starting "the crucible" because you want to win an argument.
I don't like Pinker as a public intellectual and not because of the company he kept, because of how sloppy he is with numbers, and an extremely argumentative egotistical posture. Some of his ideas are interesting.
If you're going to start bone pointing to evil, do it somewhere else.
