I spoke as someone who has experienced the various streams of MO. I mentioned that the students of rabbi shechter are relatively normal in their halachik thinking, but not 100%, because there’s influence of nationalism and their college studies.
Some of my childhood neighbors became successful in learning in RIETS and are people who I trust to a pretty large degree, and with whom i could have normal learning conversations about everything except zionism. I respect that. I would not be bothered much if a student of mine(this has happened) followed the psakim of rabbi shechter or rabbi willig.
What i don’t respect are the other elements in YU, including in the beis medrash. Go talk with the bochurim, go hear what they think of hashkofa matters. And go speak with many of the rabbis, who spew heresy about science being as important as torah.
And then read what the students write in their newspapers.
Then look at the communities the young couples create. Cesspools of immodesty and apikorsus.
