I would argue that perhaps you are just more aware of it.

no, i've been aware and wary of it, and i'm not suggesting that the ((())) stuff is in any way new. i'm saying that every tiktok comment section wasn't filled with it and takes about "them" and "you know who it is" three months ago. overt antisemitism is on the rise because isntrael has succeeded in directly tying together the zionist entity with the jewish identity in people's minds. so for the normal (functionally illiterate) amerikkkan, "the jews" are committing genocide and therefore it's ok to be bigoted towards "the jews."

around a decade ago when Trump announced his candidacy

yes, this is a primary goal to justify the need for a theocratic ethnostate. the zionist entity sees itself as being better justified the more jewish people are persecuted globally. currently the various wings of fascist thought in amerikkka are genuinely relitigating the jewish question. it is not out of the question that the amerikkkan fascist entity and the zionist entity in the future collaborate to expel jewish people in the u.s.a. to the zionist entity. in general, the zionist entity sees this as legitimizing for itself.
