“The emergence of women taking on men’s roles en masse is a very new and somewhat isolated phenomenon. It is of no coincidence that the push to have women take on men’s roles in our Orthodox Jewish culture happened at the exact particular time and place in history as the former. Our culture is particularly porous to out environment these days, and this is an obvious side effect.”
Why do you think this is a bad thing? You speak about this as if it is some sort of poison. Any new situation that emerges that isn’t spelled out black and white somewhere in the gemara or what not presents such a monstrous threat to hashkafa… and the gut reaction is to fight without even thinking about what you’re fighting.
