We all know how Caligula was dealt with.
And what they have learned is disinformation.
My granddaughter (6th grade): "Do you know what they're teaching us? That humans are killing the oceans and destroying the planet and we're all going to die from global warming."
My grandson (6th grade): "The health teacher is crazy. She taught us--boys and girls all together--how girls masturbate."
My granddaughter (10th grade): "They tell us that the Republicans are racist, but it was the Republicans who freed the slaves and the Democrats who tried to keep them in slavery."
If the US education system teaches about Caligula at all, I would expect it to be some sort of propaganda disinformation designed to justify its nefarious, anti-American, leftist political agenda and certainly not truth.
