I think Lemmy has a problem with history in general, since most people on here have degrees/training in STEM. I see a lot of inaccurate “pop history” shared on here, and a lack of understanding of historiography/how historians analyze primary sources.
The rejection of Jesus’s historicity seems to be accepting C S Lewis’s argument - that if he existed, he was a “lunatic, liar, or lord,” instead of realizing that there was nothing unusual about a messianic Jewish troublemaker in Judea during the early Roman Empire.
I was under the impression that historians more didn’t have any evidence to discount the existence of the guy than so much as distinct records of him, so because of Christianity it’s generally accepted a guy existed. But it’s been a while since I looked into it and my memory is kinda shit, I’m getting old.
