Yy, I hear what you are saying. Let’s make sure we are not combining two issues: 1) you claim that Mizrahi affected those jews that were not affected by the non religious movements. Prob true, but it is a crime in your eyes because you are viewing any cooperation with zionists as a crime. 2) that Mizrahi made their children non religious. This is a serious claim. Is it really true? It probably was true early on, but so was with other jews, in Palestine andin Europe. It was everywhere.
At the end, children of those who moved to EY did better than of those who stayed in Europe listening to r Wasserman and others.
The way you present history after that is somewhat colored by your opinion. Who started, who joined later… bottom line, Mizrahi Cooperated more and had influence on what the state was doing. I agree that both groups tried their best in unprecedented circumstances and had both good and bad Decisions. Even r Yochanan Ben Zakkai was not sure whether his negotiations with Romans were done correctly.
