People are excited that Richard Muller, lead scientist on the BEST group, was a ‘skeptic’.
Why do they think he was a skeptic? Because at one time, Muller criticized the makers of the hockey stick and supported McIntyre.
Just pointing out that there is something wrong with the hockey stick does not make you a skeptic. You can be a supporter of the consensus (i.e., ‘warmist’) and still point out dishonesty. It is allowed.
