DY: “There’s no question that all streams are different than Jews were in the past, the difference between each of today’s streams is how they have adapted to today’s reality.
Everyone thinks that they have adapted in the manner that our gedolim from the past (going back to Chazal and even earlier) would have wanted, and therefore “default” Judaism, and the others are “movements”.”
That sounds very nice except that I don’t think it’s true. Zionism was a new movement that hadn’t existed previously, and the term Chareidi is just used to refer to any Frum Jews who don’t define themselves as religious-zionists.
Chareidi is the hebrew word for Frum. There is no other word for Frum in hebrew. Do you consider Frum to be a new movement?
Were the Perushim a new movement? They were just the Jews who didn’t become tzedukim – the same way that the Chareidim are the Jews who didn’t become tziyoni.
