I don't think they post this crap in an attempt to sway or otherwise mindbend anons.
It's simply to post as much antisemitic stuff as possible, so that when normies come here the first time, it's all they see, and being as most people are not antisemitic, newbies are shocked and dismayed by all the antisemitism. Is this what Q is about, they ask themselves?
So proceed to leave and never come back, and spread the word in the normie world that "Qanons" are rabid antisemites.
