First of all - J Street is not pro-Israel. What makes it pro-Israel? Is it pro-Israel because it doesn't advocate the destruction of Israel- per se? So, then Communists are pro-Israel and so too is the PA. You only advocate for the speech rights of those who you agree with - and do not believe in free speech for the right. Therefore- you and J Street are both phonies.
