“I just think it’s changing the culture. I think it’s a very negative thing for Europe. I think it’s very negative,” he said, as if we didn’t hear him the first time with the foghorn. “And I know it’s politically not necessarily correct to say that. But I’ll say it and I’ll say it loud. And I think they better watch themselves because you are changing the culture.”

They better watch themselves because you are changing the culture. There’s a polite way to say this, but the time for good manners has long gone. The president of the United States just threatened the safety and security of immigrants the world over.

Not just in Europe, he made clear, as he continued to talk about American immigration. “We have very bad immigration laws and we’re, I mean, we’re doing incredibly well considering the fact that we virtually don’t have immigration laws,” he explained.

So now we know. The reason Trump ordered the separation of thousands of immigrant children from their parents – some never to be reunited again – was because they better watch themselves. They are changing the culture and it better stop or else they’ll get hurt.
