Shellenberger's arguments have been discredited for decades. At some point, it is just a denial of service attack against researchers with better things to do with their time when he says "fight me fight me fight me fight me" over and over. It is the same rhetorical trick. At some point, you just get frustrated and call somebody an asshole and move on.

Yes, it isn't sound logical thinking to say "tons of relevant experts in this field think this guy is an idiot." But it definitely is a strong bayesian update.
