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.
What Jesus are they talking about? That needs to be defined first. Not the one depicted in the bible that’s for sure.
A Jesus who had an apocalyptic ministry, some amount of followers, was executed by the Roman state and said at least some of the things recounted in the Gospels. Matthew and Luke are clearly pulling from some sort of earlier source, which likely had at least some accurate accounts of his teaching.
TLDR: “The one in my head, that I cherry picked from a contradictory fictional source”
