I guess you were born a grownup, but "teachers must die" is not considered extraordinary hate speech among kids.
I heard various pieces of doggerel among elementary school kids in my pubskewl years, to the effect of doing various vile or violent things to teachers. Usually the kids did not even get scolded for it, it was the same ole same ole childish hyperbole and everybody knew it.
