 They're not welcome because there is no home for their worldview. Their worldview is invade the world, invite the world. Their worldview is to bring in as much plastic garbage from China and deindustrialize our base. Their worldview is that we don't care about the American workers because they look at America as a colony, not a country. We are a nation. And you cease to be a nation when your leaders don't feel an obligation to deliver results or represent the people. A colony is just a place where you do commerce.
