Stating the Obvious and Getting in Trouble for It

When I first saw the headline: Rabbis probed for alleged incitement, I thought: great, someone called for Olmert to be killed again.
But no, it had nothing to do with that (thank God):
Deputy Attorney General Shai Nitzan instructed the police to launch an investigation against several prominent rabbis in the Orthodox community on suspicion of incitement.
Tuesday's decision followed petition filed by the Israel Religious Action Center (IRAC) back in March. The IRAC filed its petition following several media reports suggesting Rabbi Chaim Kanievsky decreed that Jews were no longer allowed to hire Arab laborers.
Rabbi Lior rules Jews must not employ or rent houses to Arabs, following murderous terror attack at Mercaz Harav yeshiva

Uh huh. And what is so terrible about that? I'm not suggesting that the Arab population in Israel be disenfranchised or excluded from full participation in democratic society. But consider:
1) Their leaders no longer call their community Israeli Arabs. They are now all so-called Palestinians.
2) When Israel is attacked by the Arab enemy, they scream for joy and dance on their rooftops. (Doesn't stop them from demanding UJA money when their houses are damaged by their Arab brethren though)
3) When Israel deigns to defend itself from Arab attacks, they protest and riot in the streets.
At what point does the Jewish leadership say to the Arab Israeli leadership: either you're loyal to this country or get out?
