Surprise? If you have a clean living room, and bring 10 monkeys into it, within 1 hour you’ll have $h!t and p!ss and other substances on the walls, furniture and floor. Monkeys cannot do otherwise. It’s their nature.
Bring millions of savages into your country, and the women will be raped, the men murdered, buildings burnt, and your money spent.
Bad analogy. It is possible to train monkeys.
