Singling out Reform Judaism - which sticks out like a sore thumb here, as it’s basically indistinguishable (as you’re using it) from liberal Christianity, which is much more significant numerically - leaves a bad taste in my mouth.
I was not intending to be antisemitic. I just think is a salient example of a religion that no longer believes in God. Christians tend to profess a belief in God right up until they become atheist, at which point they no longer attend church.
I disagree that liberal Christianity and reform Judaism are very similar. Reform Judaism tends to be far, far more liberal and secular than liberal Christianity.
