Feif, you aren’t allowed to disagree with ANYTHING I say LOL.
I do think its unfair to move directly into Meah Shearim and walk around in a bikini. Now, if you move in three blocks away, and the neighborhood doesn’t mind, then you have no (neighborly) obligation not to wear a bikini (halacha aside).
But most of the neighborhoods with new people were unsettled by Jews. They formed their own neighborhoods. They shouldn’t have to conform to the Yeshiva rules, unless they choose to.
My sister’s neighborhood is basically a Brooklyn neighborhood. Many do not have a sheichus to the Yeshiva. What obligates them to conform with a neighborhood that is miles away? Nothing.
I think the real issue may be that some of the yeshiva crowd wants to move into other neighborhoods because the real estate near the yeshiva is super expensive. So they look in the newer neighborhoods and say “Oy! How these newcomers have ruined our area.” But really, its a totally new area to begin with…
