People are not morally monolithic -- having been awful in one moment doesn't mean they can't be helpful or insightful in the next. I wouldn't listen in
to someone harassing grieving parents, but I might listen to someone who
had done that, if they were talking about something else.
This sort of hyperventilating moralistic fear of certain people makes me laugh, in its similarity to Victorian or conservative Christian communities. You cannot possibly want anything to do with that vagabond! I don't know, he has some vices, but he also has some perspective I am enriched by hearing. You don't have to fear sinners. Don't imitate them, but your life will be richer if you're less of a prude.
Milo is a gadfly. He offends me sometimes, too. And sometimes he has stinging observations I don't hear anywhere else. I don't want to listen to him every day, but I would be poorer for having never made the acquaintance. Alex Jones is energetic and occasionally unhinged, and when he says something completely insane that also happens to be true, I find it a comedy experience like no other. But he can also be a wakeup call to some of the naive views I hold. I don't want to listen to him every day, either, but I would again be poorer if I never had.
But at the end of the day, I really resent gatekeepers who want to make these sorts of decisions for me. I read history -- which means I read lots of things lots of very evil people have written. I would actually rather have the opportunity to read and study Hitler's words than have them banned on the assumption that they are too dangerous for me. I would like to think I am wise enough to judge evil for what it is, and I would like to be able to prove that to myself against real villians of history. The versions I was given in elementary school hardly illustrate the dangers. Goodness knows I can't avoid encountering dangerous ideas in the real world anyway, so what is the point of trying to protect me? I would rather be strong than safe.
People are not children. They can handle reading history's dangerous ideas, and they can handle hearing society's dangerous ideas. It is better to encounter those ideas on Joe Rogan with thoughtful and open questioning and discussion, than to encounter them quiet and unopposed in private. Strong people are better than safe ones. Victorian moralizing and shunning didn't really work out for them either.
