It doesn’t matter the diversity of schools you’ve attended, it just matters who’s story you believed. If you believe that MO is authentic Torah yiddishkeit and the frum world is a breakaway sect, then you drank the MO cool-aid because that is not the reality.
You’re allowed to be MO on the CR, but if you’re easily offended when people put down the MO, you aren’t going to have a good time. There was once a time where every thread turned into a fight about religious Zionism even if it was about something like gefilte fish recipes. That trend is not as bad anymore. I’m not meaning this as a threat, really just a fair warning. Whether you like it or not, you will be pigeon-holed into a camp here, and almost every thread is argumentative in case you hadn’t noticed. You aren’t ever going to feel like the other side respects you views. That really just isn’t how the internet works.
