Antisemitism from the left

Unlike the Nazis, who, apart from being socialists (like all of Europe at that time), were extreme right-wing. It seems that today a significant part of anti-Semitism comes from the progressive left. But it seems that this anti-Semitism is less nationalistic and fascist and more ignorant and trendy. My question is, do you think this anti-Semitism poses less of a danger to the Jewish people or do both pose an equal danger?
