[E. Pluribus Unum]

The black pastors who were going to endorse Trump were viciously attacked and had to back down because Democrats don't allow blacks to leave their plantation. They consider them to be their electoral slaves, and call them "race traitors" if they attempt to leave.

Here is a quote from one of those pastors:

Scott said that the criticism he and other black pastors have faced from for dealing with Trump has been withering.

"We've been called Uncle Toms, sellouts, coons … We have preachers calling us 'prostitutes on a pole,'" he lamented, referring to an epithet leveled by one Baltimore minister. "If Donald Trump said that, the entire nation would be in an uproar."

If they backed down and withered under pressure, then they are a bunch of cowards.
