outoftowner: While I agree with you that the reason it bothers the less yeshivish crowd when the more yeshivish crowd wears hats and jackets the reason is not because they feel bad that they are so hot.
I do not however believe that the reason it bothers them is because they dont wear it and they deep down feel they should, rather I believe the reason is because when a nonjew sees jews all over wearing the black hats and jackets and white shirt black pants, that is what they come to associate jews with, and since it looks really weird (and dont tell me its not because walking around in 90+ weather in a hat and jacket looks weird) they are afraid that nonjews may look at them the same just because they are jewish (and the less yeshivish usually have more interaction with nonjews than the more yeshivish). Im not really that good at putting down my thoughts into word so this probably didnt come out right. Oh well.
