I wouldn’t call it racism because they’d object to an Italian white Christian family moving in as well.
But definitely KJ made a private, religious village originally, and wants it to stay this way. I think KJ has by-laws regarding women not driving etc. but don’t think it can be legally enforced. So when and if it happens that they discriminate against some Chrisirtian that wants to move in we’ll argue about it.
Now it’s not a hypothetical and it would be nice if we’d all advocate for our fellow Jews when they’re right just as the African Americans or Asians would similarly stick up for their brethren.
