The author makes a good case for keeping them out - they're too clever by half. That and their ethnic nepotism makes them formidable allies of the Anti-White State. And yes, if they were dumb as rocks that would be another reason to keep them out. In short, there's no good reason to let other peoples into our Lands. It's pretty basic, but obviously only White Nationalist are going to get it. People who don't, aren't. They're something else.
