Actually there are schools of theology in both of these religions that enshrine diversity and embrace interoperability with other religions. They are just not mainstream because guess what? Mainstream religion is owned by power, and all that power is fascist essentially. Sure enough there are no true believers in anything but power in mainstream religions, start stripping them down on theology field and they reveal it.

I mean, just have a look at any works by Hakim Bey and Tim Morton’s latest book.
