That’s an old school Gnostic interpretation, and that in part lead to the development of Christian antisemitism. (See Reuther, Faith and Fratricide)

You’re missing out on the hundreds of years of Jewish scholars navigating and interacting with the text. It’s easy to understand the shift as discrete, because Jesus is a clear breaking point, but a lot of that develops from Greek philosophy interacting with Judaism. He was most assuredly influenced by Nazarite thinkers too.

Keep in mind too that Jesus said he brought not peace, but a sword. Jewish understandings of the messiah at the time were seeking a military type leader to lead them against the Romans - that threat is probably what actually got the man crucified. Read Luke 22:36.

Seeing these kinds of r/atheism versus Christian conversations is always a shit show. Everyone is wrong.
