People said similar things in my critique of Stephen Hawking. I tend to look at the content of what people say moreso than their personal lives. Not that I don't think low moral character has any affect on the value of their ideas, I just tend to be uninterested in what they were like personally while researching.
The notable exception is Thomas Jefferson, of course. People have shown me his anti-Christian or pro-democracy quotes, and I respond: "This clown knocked up his slave girl! Who cares what he thinks?"
Freud came up with most of his theories because he was trying to hide his diddling of women who weren’t his wife. Yes cocaine addiction plays an important part in that
And by the way....Thomas Jefferson did not impregnate Sally. It was one of his relatives a brother or an uncle
