To Trump and his supporters, one cannot be American unless one is white and christian.
Trump ALWAYS has to have an enemy. At every rally, every speech, every interview, every debate. There's always an enemy.
Lately, Susana Martinez is an enemy. Judge Curiel is an enemy. Japan and South Korea are enemies because they're not "paying their way.
It's how he keeps his tribalistic followers all pumped up: always have an enemy. Somebody to hate.
Trump is an expert at hating you unless you kiss his ass. And, even then, you're one slight away from becoming an enemy again whom he'll attack publicly.
The sonofabitch is a mentally deranged sociopath. How did we get here with such a man in competition to lead us? And what of his supporters, who, in order to forget their own problems, link arms with someone who appeals to their lowest instincts?
