I liked Hitchens the best. Right now Sam Harris and Dawkins are pissing me off by not talking about Catalonia or coming out strongly in favor of their right to independence.l especially from threats of violence. Dawkins supported keeping Scotland in the EU too.
Dennett also strikes me as naive in how he thinks we can still make a diplomatic peace with North Korea and live with their nuclear state that refuses to reign itself in according to a denuclearization treaty. If the US has respected their borders for 70 years and they are allied with china, then they're fine without nukes.
