"Virtually no minorities voted for Trump."  Absolutely true.

Only 12% of black folks even bothered to vote.  Only 11% of Hispanics even bothered to vote.

88% of black folks voted for Hillary.  80% of Hispanics voted for Hillary.  

The black folks and the Hispanics stayed home and therefore have nothing to complain about if they don't like the result of the election they boycotted.
