10 bucks says the text wouldn't fit well in a 5 pointed star because a 5 sided polygon is a bitch to have to fit text into efficiently ... and they couldn't make the 5 pointed star any bigger or it would dominate the graphic, so they picked a star that has a square bound in the center and didn't make the connection -> mostly because 'anti-semitism' is about 5 million miles away conceptually from a not-known-for-his-religion man whose daughter is jewish, who mistrusts a political religion that wants to kill all Jews and whose opponent is a lying atheist. ... there no 'Jewish' in the whole conceptual picture.
It IS a dumb mistake ... but it's also a very human mistake - doesn't require negligence ... just passive ignorance or a brain-skip at that moment ...
As someone said, if this is all they got, they're screwed. And if their lumpen electoriate buys this - then the bald face propagandized moronacy is beyond what I've estimated ... and I've estimated it pretty high.
