Ok well im Asian/Muslim and i think Arabs are stereotyped as being Terrorists/Suicide bombers/crazy people who chop guys heads off. But most of them are normal, civilised people like you and i. In every race you will get a select few who do not do things right by the law so i think it's unfair to say just one race are bad.
As for the situation in Palestine, i feel that the Israeli's are bullying the Palestinians just because they have more military and financial advantages over Palestine. I think the Palestinians can see no way of helping their country by taking their own lives in order to make a stand. More info on Arab stereotypes can be found

I hope this helps
