I'd say that the problem with trump's speech to black people wasn't so much that he was spewing erroneous stats but rather the way he phrased it as "y'all situation is so fukked up that you should be happy with whatever that might be (if anything)"
Imagine trying to pick up a girl and telling her "you're fat, u ugly, u dumb. U might as well date me what the hell do u have to lose"
A better approach would have been to acknowledge the problem and then state his plans for improvement and what he has to offer. Not this whole let me throw u these crumbs since u starving anyways
