Dear Avira,
Your history is still all wrong.
[like Mordecai Kaplan… You picked the most unique person of his time. There was nobody else remotely like him. Same thing with Lieberman. A top level gaon. Not many like him anywhere. There was no common denominator. These two disagreed on everything.]
But your main problem is that you only count those that live up to your standards of the group.
So the solid guys in yeshiva are obviously no longer MO. And the drop outs are. The baal habatim better be careful….
The YV has the same tolerance for heresy. In the modern day people can’t be coerced to think alike.
