Look, I've tried to be fair with the President. Some countries and their current conditions are exactly that - shitholes. Very poor conditions. He's nothing but honest and blunt in his assessment.
However, his comment is just another in a continued (rather excessive) pattern of actions that alienates and divides, and continues to marginalize people of color. After a while, you learn it's not about immigration reform for this administration, but rather, the "kind" of immigrant here that will making this country "Great Again."
