i don't know. it's called the "euphemism treadmill". when one word becomes taboo, they need another one to speak about it the same subject. then that one goes bad too. pederast became "sexual pervert" which became "gay" which became "homosexual". "retard" used to be a euphemism for "moron" or "cretin".   good dad. thank him for raising you with an ability to identify propaganda through loaded words.
