I can't speak for people, but as it relates to me personally, my own relationship with Graham was based on the way he interacted with me personally. His approach made it very difficult for me to appreciate his perspective. I do my best to withhold judgement on people until I have direct experience with them to corroborate the claims made. This approach allows me to avoid judging someone based on hearsay. It also means I might be late to the party in rightfully judging someone as a bad actor if I've only ever seen good (from my limited perspective).
As I've mentioned in comments above, I'm not as interested in exposing people as I am in exposing bad ideas and promoting good ones. From the beginning, to me, this seemed all about Adam the person which is a conversation I wasn't all that interested in, especially if the ideas put forth by Adam in Freedom are good (and I think they are).
I'm sorry to hear this has been so frustrating for you. I think in any healthy community we need all kinds of diverse perspectives. Maybe some people do have to focus more on the personalities, reputations, and identities involved. Maybe that's not for everyone though.
