You are also correct he uses codewords, buzzwords, and dog-whistles to make his "point", such that it is, while providing an escape route when people object to his stupidity or bigotry. "Othering" is very popular on the right. There is always someone else who is actually responsible for the ills they face. That said, we can't ignore when the left does this too as exemplified when anytime he says shit like this, someone always demands "What did this or that Jew say about it?" Why should that matter?! All it does is misdirects an anti-Semitic attack/misinformation toward a member of the victimized group, with the implication that is "said Jew can't be bothered to respond, then how serious is it really?!".
Jews are often the scapegoat for a variety of ills in society. Look at the second picture you used in your OP. Those Jews were murdered not only for being Jews, but because the right has placed the "influx of illegals", that is to say immigration, especially for those in need, on the Jews who are trying to "replace" the "good, white Christians" in the US. It is so strange that even things in which Jews aren't really relevant, we somehow are to blame or are behind the nefarious actions.
Name a topic and I can find a corresponding conspiracy theory in which the Jews are to blame. Financial crisis? JEWS! COVID-19? JEWS! Vaccines? JEWS! The murder of Kennedy? JEWS! Loss of one politician over another? JEWS! Porn? JEWS! Civil Rights? JEWS! GLBT Rights? JEWS! The murder of Jews/rise in anti-Semitism? JEWS!!
There is almost nothing that can't be traced back to someone, including societies/cultures/movements, blaming Jews for their woes!
