Have to what? Kill off 25 million Americans who won't submit.
I remember the Mau-Mauing, psycho babbling from the 1960s.
The 1960s Marxist-Alinsky campus radical, psycho spoiled brats were celebrated in the establishment MSM as the most intelligent generation ever! They are now arguably that very establishment that praised them and they hold themselves and their ideological issue in even higher regard.
The left is hijacking the good word American to hide their big gov communism under. Americans are not people that advocate higher taxes, banning guns, and regulation of everything from salt milligrams to slurpee size. Tell me again why they call themselves "liberals"?
