Shalom Chaim,
strange as it sounds, whereas in US, Canada, Europe one has a choice of patronizing or not muslime businesses, in Israel one does not. Almost every business here employs arabs. Arabs build roads, construct buildings, work in restaurants, clean streets, labor in back rooms of grocery stores, etc. These arabs seems peaceful and, some of them, are pleasant and amiable, even more so than Jews. Arabs are everywhere here - they seem to live very nicely with Jews. And Jews are not forced to hire them - no Kadima members are standing behind grocery's owner back and force him to hire arabs. And I kind a feel bad for young arabs who sweep the streets and wash dishes - they deserve better future, just not in Israel.
Now, I didn't go to the "dark side", I simply state the facts - that most of small and large retail business owners in Israel, religious and secular, are greedy and greatly benefit from the cheap arab labor. Most of the Jews here will not boycott businesses employing arabs - it is just impossible.
What is your take on this phenomenon since, rabbi Kahane, ZT"L HY"D never advocated forceful transfer of ALL arabs - those who want to live with Jews and recognize our sovereignty over Eretz Israel, would be welcome to stay here, without any national rights?
How would you feel, once you move to Israel, G-d willing, if you have to patronize such businesses. What would you advocate doing about a tremendous number of arabs employed by Jews?
