It is tempting to shrug off conspiracy theories as fringe entertainment. Worse, its loudest promoters seem to believe what they peddle — and millions of followers nod along as if faith were evidence. The poison matters because the claims are baseless and familiar. In 2025, the medium has changed — podcasts, livestreams, viral clips — but the message is the same: Blame the Jews. If mainstream institutions, Jewish organizations, or reputable reporters condemn a claim as antisemitic, that condemnation becomes proof to true believers that the claim must be right.
