Sexual education is fun.
In Israel, a decent ultra-orthodox child by the age of six (first class) not only knows that Adam and Eve had children in Paradise and do their commandment. But he will also hear about the fact that Kanaan raped the grandfather of Noah (they are all officially) and about Onan (guess what he did). The song can easily be heard.
Copywriters are embarrassed. Trolls are afraid of children in cowards.
