From what I can see so far, a Trump Administration would be a lose/lose situation for not only Black America but for Latinos, women, and the poor of all races.
If the country does poorly under his Presidency, the conditions obviously get worse.
However if the country manages to actually improve under his Presidency, you'll never be able to accuse a bigotted White man of racism or sexism again.
No one will want to hear it.
They'll all point to Trump and say, "Well, they called HIM racist and sexist but look how great he was for our country...so just shut up!"
Instead of being condemned for their intolerance, every bigot who seeks a position of leadership will be "given a chance".
Racism, sexism, and fascism fill flourish under that scenario.
