PBA: So what are the defining differences between this “paradigm of MO-machmirness” and a yeshivish person? Because you’re making it sound like yeshivish is a default position and everything else is just a variation on the theme. I don’t think that’s so true- yeshivish people are also more likely to have a different attitude, for example, toward kollel, toward secular studies, college, women’s roles, etc. It’s not just exterior observances and movies and singing Hatikvah.
I’ve seen “MO Machmir” families and yeshivish families where the two families were indistinguishable, but they wouldn’t be able to have a conversation where they would be on the same side on an issue. I think that MO is (or should be!) more of a state of mind, not a “what do I keep” cheshbon.
