I find when people identify someone else's usage of the "No True Scotsman" fallacy to be disingenuous, as if it's impossible to make objective statements ever. No true historian promotes knowledge which hasn't been proven. There is no evidence that a man named Jesus the Christ of Nazareth who could perform miracles and spoke to Pilate and was known throughout the kingdom as a troublemaker ever existed. There was a Yeshua Ben Hur who historically could be an avatar people can associate these fantastical tales with, but that would obviously not be real history.
