First of all Reb Dovid, being that this is your first post, Welcome and I hope you becime and active member of the CR.
Unlike @aviria I didnt grow up MO and dont carry the anger or baggage when one does a lifestyle change and am able took at this dispassionatly, I do have to give him credit, my topics of debate at 14/15 was who makes the best pizza, the best ways to break into the yeshiva kitchen, how to sneak into bais medresh late without being noticed.
The MO movement is slowly heading to the history books, its either stagnant or diminishing, MO schools are closing or tacking right, YI shuls are merging or closing, and YU has had declining enrollment for years.
My two big gripes about the MO community are ,
[1] changing of mesorah and halacha to fit the agenda at hand such as ordination of “Rabba”s, Bittul Kiddushin, Womens Hakofos, mixing dancing at weddings,mazel tov greeting on a gay marriage in the shul bulletin, elevating tikkun haolam drivel to be equal with halacha.
2. I found the most intolerant people to be MO, they would not credence to an opposing view, this manifested itself in the big way during covid when the MO opinion mattered and everyone elses opionion was irrelevant.
