Make sure you mention “Arming America” by academic fraud Bellisiles.
He used made-up research to try to advance his thesis that firearms really weren’t that important in 18th century America. And he was shown up for the bigoted, lazy, ivory tower egghead he is, trying to pass off his own lefty opinions as historical fact.
As far as that goes, the best advice you could give your pupils would be to skip higher education/indoctrination for the gun range. A bullet doesn’t lie.
