In 1995, 1/4 of Americans started to lose their minds because TV had girls kissing girls, black people, and Mexicans. 6 years later, something bad happened, another 8% of Americans lost their minds, and turned to White Prosperity Jesus, conspiracy theories, and ultra nationalism to salve their weary souls.

Then a black guy got elected president. This, combined with 20 years or growing income inequality drove another 8-10% berserk.

In response, they found the closest thing they could find to White Prosperity Jesus, Creepy Orange Prosperity Uncle, and banded behind him, in a quivering hope that he'd send all the funny looking colored and gay people someplace far away like Mexico, the capital of Africa or something, so that good uneducated people who work 20 hours a week could afford a 4-bedroom house and a Camaro, like it was when their grandpa was growing up.
