No, I've just seen Singal have "discussions" on race and completely dance around ideas and completely not engage the arguments of the black authors arguing with him. So it's not really his output, but literally that I don't trust him as an honest actor. I know there are certain things I agree with him on, and others that I disagree with him. But I wouldn't use him as a source for the things I agree with him on because it's not about what he's saying, but how he's trying to go about it.
So this is like a specific thing to Singal himself, not necessarily based in any view he holds but how he carries himself and how he conducts himself in arguments. I find him to be a bad-faith actor, and thus don't trust any of his output. I know there are plenty of people I disagree with who I find actual good-faith arguments (or at least less bad faith) like David French, Noah Rothman, Scott Lincicome, and a bunch of others I follow on Twitter to keep out of a bubble.
