The defying-common-sense part: They claim that no credible scientist departs from the IPCC orthodoxy. Counter with some names -- Richard Lindzen, Fred Singer, William Gray, John Christy, Don Easterbrook, Piers Corbyn, Roy Spencer, Pat Michaels, James O'Brien -- and they impugn their scientific credentials.
If they have to redefine peer review, they'll do that, too. And then they ask you to trust them on the dumped CRU data. After all, they're scientists.
