Not surprising at all. Ignorant racist kids do what ignorant racist adults do. This is symptomatic of a dying white supremacist ideology. The election of Trump was their last hurrah, that's why they voted for him in earnest. They know the U.S. is becoming more ethnically/racially diverse, not less. By 2020, U.S. Census estimates 56 percent of people under the age of 18 will be from a minority race or ethnic group. And, minorities will be even a bigger share of the electorate. 

Again, to those who voted for Trump... you voted for this? Resentment, fear, and ignorance aren't going to do anything to help the white working class; they'll be worse off under a Trump presidency. He's not bringing back jobs from anywhere. The world economy has continually evolved over decades. Don't you get it yet? Tech advances are like death and taxes -- a certainty of life. Those jobs are gone forever. Trump will be a one term president, unless he gets impeached, which is likely according to Vegas odds.
