i grew up in a modern orthodox family. when i was a teen our family joined a yeshivish community. but when we lived in the mo community, many mo community members looked down on frun people who werent mo. looking down on others is something i never experienced in my large yeshivish community.
Since you are a “user not found”, I have to assume you are Joseph.
Sorry. If you aren’t, please repost under your “real” screen name.
That being said, I don’t think you are incorrect, but I don’t have first hand experience (a benefit of living in a very mixed community). I haven’t seen the MO look down on chariadim here (at least that I can remember).
