He wasn't making any historical claims? He was offering his expert opinion on your authors claims, he is an expert historian, he pointed out that the work of the author you cited was never submitted for peer review thus it falls woefully short of the standard historians would accept, the article gave expansive explanation as to why, but you have ignored these again, failing to acknowledge your error, and laughably demanding that a personal opinion be peer reviewed? Do you even know what peer review is, or how and when it is applied?
Yes, and he pointed out the bias of the author in the claims you cited, instead of sulking because this expert happens not to share your beliefs, you might want to read his criticises, and acknowledge what they mean for your BS claim. Sadly you seem to have settled into this "nuh uh" response as your MO to all arguments.
For what, Carrier was not making any historical claims?
Are you saying Carrier's criticism were incorrect? So you are asserting the author you linked has in fact submitted his work for peer review? This is great news, you might want to email Dr Carrier and let him know. Dr Carrier by the way was offering an expert opinion exposing the flaws in the work of the author you cited, not making any historical claims himself, opinions are not peer reviewed, why would they be? If you think there are expert historians out there who accept the claims your author used, despite refusing to submit his data for peer review, even after multiple requests from expert historians like Dr Carrier, then you're again woefully mistaken.
