i would bet money its sone zionist invention to exclude muslims since its essentially used as a a distinction between the “civilized” (wtf are judeochristian values and why is it so important to uphold them?) and the others.

Not Christian, but purely from a historical perspective it is pretty clear cut that Jesus was a Jew, Christianity arose from Judaism (as Paul alludes to many times), Judaism has changed a bit too, to be sure, but it is still roughly the same religion. Islam then was adapted from Christianity.

That’s why many use the term Abrahamic religions, rather than Judeo-Christian, as that also includes Islam
