You know, we had separation between church/religion and state for a good reason.

Who has it? Certainly not Israel. Or America. The U.K. does far better in practice, but not fully - nor does it claim to be.

It's "separation between church and state". As in: the institution of The Church. "separation between religion and state" doesn't really exist anywhere, and can't really exist, because it would basically be a thought-crime. For example Joe Biden is a Catholic and I'm some of his actions have almost certainly been inspired in part of fully by his Catholic beliefs. It couldn't be otherwise as being Catholic is part of Joe Biden.
