He's new to me. Will check him out.
What you're describing is the very problematic "all or nothing" viewpoint that tends to be more prevalent on the left than on the right. It's like you can't work together unless you are in 100% agreement about everything, which is going to necessarily be a small percentage of people. Meanwhile there are issues the needle could be moved on where there is agreement by like 80% of the population, but it just doesn't happen because of this all or nothing mindset. Both sides of the ideological divide do it, but it happens more on the left.
I think it would be impossible for far left and far right to work together on anything at this point. I see anarchists as something else entirely though, and hope to see alliances with the left there.
