They are Americans, and three of the four were born in America. How do you tell three people to "go back to the countries you came from" if they are FROM AMERICA?
And I find it ironic that all the people saying "if you don't like it leave" are also saying "Go fix your own broken country. So which is it? If you don't like the way things are going in your country you should leave, or if you don't like things you should try and fix them? Because those women are AMERICANS who don't like something and are trying to do what they view as FIXING the situation. Whether they're right or not, whether you agree with their stances or not, they are doing EXACTLY what he told them to do already. try and fix their own country. He just didn't seem to understand that their country was AMERICA. And you have to wonder why.
And speaking of "If you don't like it, then leave."
Donald Trump did nothing but whine about America being messed up his whole campaign and into his term, and no one ever stops to think that the guy saying "if you don't like it, then leave" complains more than any of the people he's saying that to. Hypocrisy at its finest.
He told American citizens of color, three of whom were actually BORN IN AMERICA, to go back to the countries they came from. There is a basic understood racism to saying "Go back where you came from" to Americans of color. If you don't think that's true, then walk up to any given black guy on the street and tell them to "Go back where you came from" and see how fast you get your butt handed to you.
