I haven't heard of any who won't take the highway between Jerusalem and Tel Aviv, which crosses the "line." And I don't know how many actually are careful to avoid Jerusalem neighborhoods like French Hill, Ramat Eshkol, Ramot and Giloh which all have residents who follow Leftist ideology. And I'm not sure that there are many who also boycott Jerusalem's Old City.
But when it comes to communities like my very own hometown of Shiloh, they act on their "moral principles" which in actuality promote apartheid, pure and simple.
I've never been able to understand how promoting the segregation of Jews, forbidding Jews to live in certain places can be considered moral. During my recent visit to the states, I spoke at the Chabad of Jericho-Syosset, Long Island, and opened my talk by telling them how thrilling it was for me to speak there, because over the years when defending my right to live in Shiloh, I've frequently used the fact that since it's acceptable for Jewish to live in Jericho*, Long Island, why shouldn't Jews be able to live in the original Shiloh, Land of Israel.
These very same people who want to keep Judea, Samaria, Jordan Valley etc judenrein, which was the Nazi plan for Europe and then the world, are outraged when for security reasons Arabs are inspected or kept out of certain places. There are thriving Arab villages near us, but in Arab countries like Jordan, we are not welcome to live.
I find this principle of not wanting Jews to live in our historic homeland (or any place in the world,) inexplicable and totally immoral! It's out and out antisemitism cloaked in faux moral poppycock!
*Today, there is no Jewish community in the original Jericho, which is southeast of Shiloh. During Biblical times, after the Exodus from Egypt and forty years in the wilderness Joshua brought the Jewish People into the Holy-land via Jericho.
