How is A not B?

As part of another post not finished, Ethon took a look over at the nameless one's twitter feed where he has posted a talk.  Now, not to be snarky, but it appears that the nameless one has really put his hand on the problem with discussing climate change, and, it is summarized in one slide, to which Eli asks how is A not B

This may not be the point that the nameless one was trying to make, prescribing more interchange amongst the sides, but Eli asks who blocks more honest bunnies than the nameless one?

And why was he not struck by the contrast?  Also for Fernbach et al.
