Typo – “the moment I got to college” should read “the moment they got to college”. In an case it is an exaggeration. The trajectory of the MO dropout in my day was – one to 2 years at an RZ yeshiva American program in EY – one year exposed to the ‘classics’ in college, then the decline beginning with lax shul attendance, eating questionable hechsherim, total flaunting of disrespect for negia rules, attendance at conservative minyanim, and then total assimilation.
