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 mean… maybe. He was writing about events 150 years ago in another country. He may not have had direct knowledge of them. Think about how contentious history can be today with the benefit of modern documentary evidence, professional historians, etc. and think about how uncertain things under such distance would be back then.
