I grew up in the same YI as one of the more controversial figures in OO.
So my MO origin credentials are solid. Based on that I emphatically state that you can not argue that MO is as makpid on “regular” halochos as the charedi community.
The women did not cover their hair, the girls were not tzinius. During the summer the counselors in the mixed day camp had no problem mingling in swimsuits. My friends were not shomer negia (or worse). The women kept starting clandestine simchat torah minyanim so they could dance with the torah etc. I could go on all day long.The final straw was my interview at YU when I visited my friends brothers already there. The walls were bedecked with inappropriate posters. For them a religious experience was strumming a guitar to some goyish nigun while smoking something illegal (at the time). I went straight to Ner Yisroel (which is not MO)
To me the over riding philosophy of many was “religion on my terms”. Sure there were good men, graduates of YU who were shtark, but it felt like a losing battle against those always trying to push the boundaries.
The OP is not wrong in his assessment (just his tone). MO is devolving into a hellinistic culture. Blending secular with religion.
Even your screen name is borrowed from secular culture.
