I think your general idea is right, it sounds reasonable that the insane cancelation mania can bring some conservatives to dig into deeper holes. It is probably what enabled the recent right shift in politics. As to Blow specifically, I've watched his streams quite a bit. I've always had sympathy for him and have been able to relate to his opinions a lot (about software in particular). But I can see how some other people could take offense from the way he's presented his stances.

I say that as someone who once made him angry myself when I live-commented in one of his streams because I had a rare disagreement. I was maybe not in shock but at least startled by his reaction. I had presented my disagreement relatively casually.

Now, my impression is that he's tuned down his considerably and developed a more well meaning stance on things over the years. Recently I've found him more on the side of "here's how most people are doing this, I don't like this, maybe I don't think it's sustainable or how you get good results, but anyway here's what I like to do instead, make of it what you want".
