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’m so puzzled by this insistence that all who analyze religious history must be religious nutcases. Even if you write off all the scholars who are religious, religion still exists as a concept in the world, and in the same way you don’t have to be a virus to study virology, you don’t have to be religious to study religion. There are plenty of atheists who are deeply interested in religion, if for no other reason than the massive impact it has on all our lives.
