There is not an easy answer and you cant do it for EVERY town, such as Brooklyn, since there has to be places for OTHER cultures and “looks” to grow also.
The problem is given US law its hard to preserve the look of ANY town, let alone every town. This is not antisemitism, its just an affection for ones own culture. There is a difference.
Much of New England for example has a certain look and feel the local populace wish to maintain. This is not antisemitism.
