This is a common position but it ignores the reality that, for too long, too many Jews have supported, promoted, enabled, funded Zionist Israel as it has committed some of the worst atrocities in human history.
Zionism is and has been Judaism for all of its existence. By omission or commission, Jews are accountable for the wrongs done in the name of their religion.
For 76 years Israel has claimed to be the Jewish State and most Jews have allowed it to do so, sending money and their children to be brainwashed in a sick system called Birthright. Most have had lovely holidays in the Israel bubble, ignoring or denying the evil injustices and daily atrocities inflicted on the native people of the land they call Israel, Palestinian Christians and Muslims.
Having spent time in what is called Israel and been lucky enough to drive around Occupied Palestine when one could, as a follower of no religion, but as a believer in the humanity of all and equal rights, I was horrified at the levels of racist hatred and bigotry, openly expressed to all, by Israelis. They are deaf and blind to their own evil and have always been for that is the nature of a supremacist culture.
No-one who has spent time there would be at all surprised at the levels of bestial savagery and sadistic cruelty Israelis have inflicted on Palestinian men, women and children for 76 years. They really do think they are subhuman. They really do think that magically, it is the homeland of Jews and non-Jews have no right to exist in it, except as compliant slaves. The Zioraelis make the Nazis look positively benign.
In this age of technology it is not enough to say they did not know and indeed, there have always been some Jews who did know the truth of the State of Hate and Death, Ziorael, and who rejected it from the start.
But, any study of belief systems and mental function in Judaism and most Jews, not all, but most, reveals the vulnerability of Jews to become cult-like in their paranoia and self-serving aggression. They may not know what they do but they should know what they do.
