Yeah... because it's not about him. He wrote what he saw and was told. His personal failings, if any, simply make him human.

You can judge him. The way you do that leads me to believe that you're a liberal, condemning people on one hand while preaching tolerance for other people to follow.

If he was an incel, a stoner, or even gay, would that make him less credible?

Well, the world is drifting towards destruction just as it was prophesied. These are the last days.

in the last days [a]perilous times will come: 2 For men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, 3 unloving, [b]unforgiving, slanderers, without self-control, brutal, despisers of good, 4 traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, 5 having a form of godliness but denying its power. 

AI will not be the destroyer or the savior.
