Wow that got crazy. Sm29 was just trying to make a distinction between MO and yeshivish communities in LA. Yes, they could have said it better, but you being a smart person should have understood what they were trying to communicate and shouldn’t have incited sinah with such an angry post.
That said, golfer’s personal anecdote is nice, but has nothing to do with emes. You think you’re promoting unity by claiming to be from a mixed family, but then defeat that purpose by claiming that its davka MO people that insult others. If you were really honest and fair, you’d be modeh that both chareidi and mo people can be demeaning of others- it’s not a hashkafah problem but a human problem. At least the MO don’t accuse chareidim of being apikorsim, amalek, and sonei Hashem. It’s probably less bad to make fun of a minhag than to call another Jew an oved avodah zarah (see Hakatan’s posts, l’mashal).
