I've said it a dozen times and I'll say it again. Be careful with any group claiming to represent Jews or Judaism. The Left and the Muslims are now famous for claiming, 'Jews for this' or 'Jews for that', even if there is not a single actual Jewish person involved in the protest, or charity, or movement. It is usually a ruse.
That doesn't mean that there are not real true crazy Israelis and Western Jews out there, who seem to support Islamic terrorists over Jews and Israel. There certainly are self-hating Jews like this. I am only advising that everyone or every group claiming to represent a Jewish cause is not automatically Jewish. Most of the time, with a little digging, you will discover that the group is primarily antisemitic Leftists, or Muslims, without a Jew in sight.
