Yes, and saying you expect a rigorous work from an historian with good academic credentials is not a logical fallacy.
If we followed your logic, we should discard all opinions coming from experts renowned in their particular field, because that would be an appeal to authority.
Basing one's assessment on solid work is not the same as citing a public figure with no expert knowledge on the issue.
