I’m didn’t scour this article but is it sure seems to be conflating anti-Zionism with antisemitism.
The only evidence of left wing antisemitism I see on there with a quick search is a single anecdotal quote from one Jewish person who says “The antisemitism in the classroom came from a left-wing contingent”. The incident being described seems to be someone writing “fuck isreal” on a chalkboard. Another was kicked out of a sexual assault support group for posting this on instagram:
Israel is not a ‘colonial’ state and Israelis aren’t ‘settlers.’ You cannot colonize the land your ancestors are from," Blotner wrote.
Meanwhile the right wing attacks are stuff like white nationalists literally murdering someone they thought was Jewish, and flyers with antisemitic rhetoric.
This article is a joke. (Fuck Isreal)
