For some reason you're willing to drop the context.

He's talking about people coming through the border without being vetted, who are dangerous to the country.

Do you think that people should be able to come into the country freely without any vetting at all?

He was pointing out a specific problem, maybe your imagination turned that into the much more general "all immigrants are bad" when he's never actually said or suggested anything of the kind?
