I’m a Jew and I’m saying the word God right now… as with anything else, religiosity varies pretty significantly, but because Judaism is a ethnoreligion and because it places such an emphasis on debate and dialogue, it’s one of the few religions I know of that’s more or less compatible with being an atheist.

There certainly are a ton of Jewish religious fundamentalists (called haredim, folks in the US are probably familiar with “ultra-Orthodox” or ‘hasidic’) but they’re actually the minority, and even they vary widely in their beliefs.
