Sooner or later, this crap will have to be dealt with by the left,

and the question is whether they'll kick it out, or just embrace their inner racist and demand more.
It was there that, as the women were opening up about their backgrounds and personal investments in creating a resistance movement to Trump, Perez and Mallory allegedly first asserted that Jewish people bore a special collective responsibility as exploiters of black and brown people—and even, according to a close secondhand source, claimed that Jews were proven to have been leaders of the American slave trade. These are canards popularized by The Secret Relationship Between Blacks and Jews, a book published by Louis Farrakhan’s Nation of Islam—“the bible of the new anti-Semitism,” according to Henry Louis Gates Jr., who noted in 1992: “Among significant sectors of the black community, this brief has become a credo of a new philosophy of black self-affirmation.”

Looking over this, two things come to mind: power and money.  Power over other people's lives, and lots of money.  And hanging around with people who hate Jews.  White people are bad, but Jews, well, REALLY bad.
On March 11, 2018, the Women’s March had their biweekly phone call with national organizers. The public controversy had started to explode over Mallory’s attendance at the Saviours’ Day event, during which, in the course of a three-hour speech, Farrakhan blamed Jews for “degenerate behavior in Hollywood, turning men into women and women into men.” Angie Beem, president of the Washington state chapter, remembered that phone call.

All the 'intersectional' crap boils down to this at the very end of the article:
...“We don’t have to call it the Women’s March. I think we still have an opportunity to pull this together. But it can’t be the Jewish women’s movement or Black womens’ or White womens’ or the Spanish women’s movement. We just need women voting together.”
Remember all the crap about 'white women don't think/care/believe/vote right!' noise that's been going on?  These people don't seem to understand that what they're demanding is 'Women must vote together the way we want them to, and if they don't they're part of the enemy'.  And people don't always vote the same ways because they don't think and believe the same ways.  But they're demanding that people do those things, just like a lot of activists demand blacks vote and think certain ways or they're not 'real' blacks.  Sooner or later that crap's going to blow up in their faces, and I hope it's soon.  Saying "We want change!" is fine, but when you're demanding "We want you to be what we demand for the change WE want!", well, that's not good.
