OOMIS- I will not deny or agree with yoru statement because I’ve met many superior feeling yeshivishe pple like you wrote and I also came across many of them who are so outgoing and accepting of “outsiders”.
But let me ask you something- Have you ever met a modern person that does NOT think THEY are superior? I have yet to meet that modern person who accepts chassidishe pple. They all think Yeshivishe pple are absurd, narrowminded, withdrawn pple and that is very far form the truth. How about looking at it that way.
Each to their own- everyone feels right about themselves. Thats it.
