The dismissal of the counter-argument is "any history book...", an appeal to authority of the type that is actually fallacious (it appeals not to any actual authority nor to anything nor demonstrates that there is any such authority
I was making no appeal to authority that I would need to cite references for.
That's what makes it fallacious. When one appeals to scholarship one is implicitly appealing to the arguments not only made by an expert but to the community of experts who (once the piece has passed review) are then able to really review it. It is an appeal to the arguments, not some nebulous collection of "any history book" or "historian" but specific sources making specific arguments based on specific evidence & logic and which are evaluated by similar experts making similar arguments and counter arguments.
You mistake the fallacy for valid argumentation and substitute it for the actual fallacy.
Ironically, I can't demonstrate this as (having already cited sources on argumentation, logic, and fallacies by experts) I can't refer to real arguments by experts without being dismissed with your "appeal to authority" nonsense while you can make whatever claim you like an appeal to "any history book", "historians" (whom you refuse to name), and any other claim you wish because you base these on nothing. Given your understanding of what constitutes an "appeal to authority", one could simply say "studies show" and follow this by any claim wished so long as one didn't actually have to cite any studies.
