“The difference is that when a Sephardi does something contrary to the Torah it’s because he is Tinok shenishba, or because he grew up that way, or because he knows what he should do but doesn’t feel ready, etc etc. But the Reform movement was BESHITA.”
You could easily argue the complete opposite and say the Sphardi guy knows better because he goes to a real shul, but the Con/Reform is a tinok shenisba.
The point is, Joseph’s claim is completely untrue. There are non-observant Sphardim in America. It might be less of a majority than it is with Ashkenazim, but it’s not “almost exclusively” an Ashkenaz problem. That’s just frum white apologism.
