Lol!
But, you really have no idea about the mesorah of the non orthodox. They stop observing long before they stopped believing. It’s hard to differentiate the fringe Orthodox and the not based on beliefs. But when it comes to observance there usually is a big drop off.
I’m trying to tell you, that the yeshiva outlook of yesteryear is still not popular today. Even though the yeshiva community has grown substantially, the purity of it’s ideas is still not widespread. The majority of the yeshiva literate, get more of their outlook from the frum media, than from a bona fide Rosh Yeshiva.
Most of the topics on these pages that have a yeshivish versus from outlook to them, have nothing in common with what a Rosh Yeshiva would actually say.
