I've written my share of articles that the far right and the far left are just mirror images of the same noxious package of creating their own gated community where they can decide who enters and more importantly who they can choose to throw out. The only thing they agree on is that the other side is wrong in every respect and 'they' are the reason things aren't perfect. I'm reminded of The Phantom Tolbooth in which the rulers of two disparate kingdoms have made up their mind whatever the other agrees with they disagree with. A child points out to one of them that if they have agreed to disagree on everything, they are truly in agreement. What's been happening at universities in New York where I lived has made it crystal clear, and your argument proves this perhaps best than anything: I guarantee you the majority of the students protesting couldn't find Israel on a map before or after this and have no real understanding of the Palestinian-Israel conflict. But I can see many of them seeing no conflict between their marching for Palestine in the day time and being against Trump because of his behavior at Charlotteville in the night time and not seeing the contradiction. In America, Jews are among the opprsessed, in Israel they are the oprressor. I can imagine they genuinely believe that some of them marching for Palestine are not anti-Semitic They believed that if the people you hate don't share your values, that you're not a bigot.
