I wouldn’t say “it was okay back then”; 17 year olds today vs then is something that is night and day.
Also The way I see it, differentiate a persons personal life from whatever contributions they have from their professional life. A good example is Michael Jackson. You can love his music and hate him as a person. So it’s more split the legacy.
This also being said, I’d erase every pedo from the face of the earth given the chance.
