You're effectively calling for some sort of cultural revolution that stamps out anti-Semitism through proper education. Seriously we've tried this with other topics, all they're going to do is say you're indoctrinating children, then you'll inevitably fall into a defensive position where you feel like you have to back it up with numbers and eloquent arguments. Bam, they've won because there will always be a first movers advantage with information: your opponent can now make an outrageous claim that people see, internalize, and then never see your rational follow-up to. You're all so incredibly terrified of censorship when the real terror is right in front of your eyes: a torrent of information, engagement, and half-consumption.
This is so incredibly tedious. I see the same thing that I'm describing here happen with any number of semblance of social progress: homosexuality, trans rights, even marijuana legalization. This cyclic pattern has to be hell, I can't fathom any other possible explanation for such a thoroughly trained helplessness.
