Because they haven't made any contributions to " peace" which is why there will never be a Palestinian State. Let's hear from one Pro Palestinian Kool Aid Drinker what proposals Abbas put forth that Israel rejected. It's a fair question.
You children cannot grasp the difference between a person siding with Arabs and a person not siding with Israel. I'm sure you cannot even decipher the meaning of that so allow me to put it bluntly-
Other than the fact that there are people throughout the ME (Jew and Arab) who are stuck in the middle of conflicts to which they are uninvolved in any real sense, I could not care less if the entire region blew up and obliterated every single person there, regardless of their race, ethnicity, or religion.
I do see now why there will never be peace though.
