The movie obviously doesn’t depict a eugenics program, but it makes the core argument of eugenics: if human breeding is left uncontrolled it will lead to “stupid” people breeding more.
Correct! It mandated eugenics in real life, in the early 20th century. I didn't say that the movie shows eugenics happening. I said "the film itself implies that the idiocracy is due to stupid people breeding more, a classic tenet of Nazism and eugenics alike." Work on your reading comprehension.
