Patriotism is racist.
Borders are racist.
Voter ID is racist.
Citizenship is racist.
Rule of law (equal justice under the law) is racist.
Property ownership is racist. (Can't call it a crime if it's under $950.)
And so on.

Convince the people that they wanted and voted for this.
Keep them ignorant and afraid.
