The appearance is that you are making it about (or at least it is important to the betrayal) that they are Jews. If you compared him to Benedict Arnold, no problem. While Jews certainly can be disloyal, even traitorous, it is important to realize those are common stereotypes applied to all (or most) Jews, therefore, drawing a conclusion that Kushner (a Jew) is like the Rosenbergs (Jews) starts to look like a pattern is emerging. Recently, the POS Wayne LaPierre of the NRA spat out all kinds of bullshit, but this was what raised eyebrows, mine included:
"History proves it. Every time, in every nation in which this political disease rises to power, its citizens are repressed, their freedoms are destroyed, and their firearms are banned and confiscated. It is all backed in this country by the social engineering, and the billions, of people like [philanthropists of Jewish lineage] George Soros, Michael Bloomberg, Tom Steyer, and more."
All Jews! He also singled out Karl Marx, Bernie Sanders, and Senate Minority Leader Charles Schumer. Guess what
they all have in common?!
So, as a Jew, I suggest you stay away from the Rosenberg analogy and take a lead from Rep. Lieu and spell out Kushner's disloyalty clearly and make sure your objections can't be painted as Kushner's disloyalty having
anything to do with his religion/ethnicity.
