I don't know the facts of the case, so I can't necessarily say with authority that such-and-such a statement is inaccurate. What Rebecca has written is interesting, certainly, and it certainly fills out some of what Dunning has made in his "official" statement. Which is true? I don't know. However, you can absolutely put a spin on truth, and this is what I believe Skepchick is doing. Notice, in fact, that not once in Rebecca's analysis does she say "Brian is wrong about this" or "this is a lie". Most of it consists of pointing out things that Brian omitted from his statement. Both statements can be true without contradiction. However, the Skepchick statement is clearly intended to discourage people from supporting Dunning in any way.
I don't believe that Skepchick - particularly with their history of hostility towards Dunning in general - can possibly be considered an objective commentator on this subject. Skepchick is not, and has never been, a non-political non-partisan dispassionate disinterested reporter of facts. They have an agenda, and in this case their agenda is anti-Dunning. The final sentence shows Rebecca's clear bias. She doesn't like him, and you shouldn't too.
But as someone recently said, this is the Internet - which means that either you're with us, or you're literally Hitler.
