Feif,
No body cares what you do on buses in your own neighborhoods or were your wife walks.
The people of New Square (and Meah Shearim etc.) go to great lengths to seperate themselves from the society at large. They put signs outside their neghborhoods and make sure evreyone knows what their standards are. If you choose to go into their neighborhoods and do things they specicfly do not want happening there you will get harrassed. There is nothing to get all self rightous about,it is not something specific to religious groups either.
If a neturei Kartanick walked into were you Daven wearing a Palistinian flag would he get harassed? Probably.
If you walk around in the Arab neghborhoods in the west bank wearing an isreali flag will you get harrassed? Probably.
There is nothing to get all self rightous about
