"Most Israeli Arabs openly support Hamas and Hezbollah and refuse to be called Israeli."

I don't believe this. More importantly, even most Israeli media doesn't seem to support this. For example, what you say seems rather contrary to what Haaretz reports:

"A vast majority of Israeli Arabs would support a constitution that maintained Israel's status as a Jewish and democratic state while guaranteeing equal rights for minorities, according to a poll whose results were published on Sunday. "

That doesn't sound much like support for Hamas and Hezbollah.
