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.
UsefulCharts just released a youtube video on the topic. The argument is basically “the earliest documents referencing Jesus aren’t explicit that he was real but on the other hand it wasn’t long before he was treated as real”. Basically there wasn’t a lot of time for myth to be reinterpreted as history.
Personally I’m ambivalent, Sherlock Holmes wasn’t real but he may have had a real effect on criminology. People may confuse his historicity. Compared to Houdini.
