If this was a discussion about his Uber article, then I think it would be entirely on point to suggest that he appears to have a biased view that may call into question his conclusions.
I went and read that article since you mentioned it, and I thought it was halfway interesting. Controversial, opinionated, unfair to some Muslims for sure, but he did raise some legitimate points. Shouting him down as racist would be easy, but I think the cultural questions are very legitimate in the modern, diverse world we live in. Even if they're uncomfortable.
Plus, the point nearer the end sounds very legitimate on it's face. Is it true that there are a fleet of really nice cars being driven by people who seem unlikely to be granted the funds to buy them, and then used for ride sharing? If that is in fact true, it would indeed be good to know why. I'd argue that the economics of Uber should make organized crime uninterested, but maybe I'm very wrong.
