Don't blame Trump, blame the ignorant, religious racists who support him. He is only reflecting what a lot of Americans, sadly, already think. Which begs the question, why do a lot of Americans think that way? I blame bad parenting. Ignorant parents preaching ignorance to their kids, who have no choice but to believe what they're being told. Why else would anyone on Earth believe the Noah's Ark story? Because their parents told them it was true.
