You're pretty much on point on everything you've just said. Religion isn't non-discriminatory as people may proclaim because, after all, it IS a business where they have to acquire and accumulate new followers to keep themselves afloat, even if it means referencing that those who don't follow their faith are "evil" or "lost". It's self-empowering psychological mechanism to the sheep who covet in their bloody mess of convoluted irrational logic.
One thing people here tend to overlook regarding the "historical" account of Jesus is that
there's no real evidence outside of religious accounts pointing to his existence, especially with all of the absurd supernatural references implemented there. If anything, based on how Christianity started, [tacked on books based off of the Torah with pagan ideas implemented] it wouldn't be far fetched to proclaim that Jesus could be nothing more but:
A) A collection of people/hustlers who claimed to be a prophet.
B) A single person or a collective who never had any affiliation with Christianity, but rather (a) worldly scholar(s) who traveled to promote spiritualism.
C) Just a symbol of an institution wanting to give people a sense of hope.
