Leftism is a cult. You are either 100% on-board with the latest thing. or you are expelled from your peer-group. One current thing which has captured Leftism is "solidarity with Palestine".
Sorry, but your former friend is a Jew Hater……..she just didn’t have the courage to tell you back in the day. And the note her family could not travel to Israel was also a lie.
Their fake religion teaches them it is fine to lie to non-Muslims.
Sorry, really.
