ok so reverse the senirio.
My parents moved into a mostly DL apartment building in EY close to thirty years ago and it took a year for the first person to say shabbat shalom and another two years for some other neighbors to do the same.
I do not write this to say lason hara but to say that there are people who are menschen and people who are not in every society and the only ones we can change are ourselves. By changing ourselves PERHAPS we can cause others to change. If all we do is say disgusting then we have not even tried to change ourselves.!
