Not here to defend Doc however it seems like the general public does not really care too much about this controversy. He only lost 13k followers on X, and 50k subs on Ytube.
My personal view is that the only way to get "canceled" is to cancel yourself. If you're a great entertainer, the majority of your audience just tunes in to have a laugh, not to judge you as a person. It also helps him being a character and not Guy Beahm.
