I would like to know how these Reddit atheists are going to convince Jewish people to give up Judaism (and not have them replace Judaism with Zionism).

"Eradicate" is overly charged. I don't see any reason why ceremonies or cultural traditions would be erased by providing more scientific education to the masses.

The knowledge of our ancestors can still be taught, and traditions upheld without literally believing that there are dieties or ghosts or whatever.

I dunno, this just strikes me as the "veganism is flawed because indigenous people should be able to hunt" argument, but applied to religion.

Holy shit no. Though like with what 9to5 said any actual changes to religious or spiritual practices would be long after our times, but again there's a bit of a false equivelency between exploitative structures like centralized churches and general practices of indigenous cultures. I have no issue with individual practice, just the structures that can arise from them.

You're overcorrecting due to the shitiness that is new atheism, and willfully blinding yourself to the issues that stand with organized religion.
