1. Most Israeli Arabs face the same sorts of job discriminantion as hareidim (being from a traditional non-western culture and not serving in the army).
2. They are forced to speak a foreign language in dealing with the government, and are forced to deal with a government consisting almost exclusive of other groups.
3. Many if not most Israelis wish to get them to leave the country.
4. As with hareidim, if they give up their religion, culture and lifestyle they will no longer be discrimianted against.
P.S. The US also disapproved of Hamas kidnapping and murdering the three Jewish boys – butg whereas Hamas is regarded as an enemy force, the Israelis are a client state (a little more independent than Puerto Rico or Guam, but less than being an independent sovereign country that could exist without American support).
