This is where you lose me. The wild generalisation that anyone attending the protest against a conflict is a monster is an absurd take. Along with you using the term antisemitism to suit your needs rather than what it actually means (both dawaxaman and greys agree on that point FWIW) and making outrageous claims it's hard to see any reasonable person agreeing or even seeing any merit in what you're saying.
I know it's part of the online persona to never admit fault or just that you're plain wrong about anything but I beg you, consider the language you choose to use. I don't doubt that there were monstrous people who were part of the protests (yes on both sides yada yada) but also some genuinely nice people who want an end to either full scale wars or the brutal attacks such as the hamas attacks on the music festival and others. Labelling them all as monsters just isn't accurate, nor productive.
I'm anticipating an ever so hilarious TLDNR style post in response and if you want to take that childish route I get it, but maybe a slight introspective look at making sure what you're saying isn't inflammatory, would add more weight to your points imo.
