Why Israeli Arab are rejected in the Arab world?

I feel sorry for you but as an Israeli citizen you aren't allowed to visit Lebanon and Syria anyway - it's against the Israeli law. So you get short changed by both sides. It'll take a lot of time and work to change the situation so that Israeli citizens, Arabs, Christians and Jews can visit Lebanon or Syria on their own pports. DOn't give up hope. You can visit Egypt and Jordan without problems on an Israeli pport.
