You think poking fun at a politician is in the same ballpark as terrorist pro-murder propaganda?
Don't be disingenuous. The point isn't about political humor, it's about INDOCTRINATING SMALL CHILDREN WITH POLITICAL PROPAGANDA and it is definitely in the same ballpark - whether it's about making murder a joke or promoting fear of, disrespect/contempt for a politician disguised as "humor".
My mother had a master's degree in early childhood education and I soaked up a lot of that along with reading a bunch of Piaget and even (wait for it) Naom Chomsky about how young minds develop. If you think such things are harmless you need edumacating (sic).
