How is that going to help him at this meeting? He already won the election, so he doesn't need to court the racist vote in that meeting. I think his goal in the meeting was to get African countries to accept deported immigrants. I'm sure he'd also like to grab any minerals that they might have. None of that has anything to do with his racist voters. I can believe that he was being condescending in order to put them in a weak or defensive position just because he likes to do stuff like that. I can also believe that he's dumb enough to believe that complimenting him in that way would help in negotiations. In fact, that is what I think happened.
By the way, I did not know that English was the primary language in Liberia, so that's not why I called him dumb in this instance. I do know that there are countries in Africa where English is the primary language, so if I hear an African speaking perfect English, my first instinct is to assume that he is from one of those countries. I would think that someone who speaks with international leaders on a regular basis would be able to figure that out. I can't assume that with Trump though, because, although I know he is very skilled at marketing and sales, I have seen no evidence of intellect from him ever.
