Now isn't the time for platitudes. It's time to buy a gun if you aren't white and male. Trump won because of white people, including college educated whites (by 1 point). They voted for him, he's their macho man gonna make America safe for the white male pussy grabbers and Christian rapos. 
Ultimately it was all that pent up rage at having an educated black man for president for 8 years. It's literally jealousy. Jealousy that some black people have moved up the economic ladder. The ignorant undereducated whites just popped their pills and drank themselves into a stupor while non-whites got competitive. 
Trump is the president for white people. The white supremacist heartland (and rustbelt) have spoken. The whites have fallen into line and are ready to do the bidding of the 1% even against their own self-interest because they are first and foremost racist.
