“I lump them all together because frankly, the women I’ve met from Hadar/Drisha were interchangeable frumkeit wise with those in YCT. And they say the same things.”
I know a lot of people affiliated with all three of these institutions and anecdotally, I don’t find that to be true at all. There is some, but not much, hashkafic overlap between Hadar and YCT. Drisha is an entirely different group.
