in a nutshell

In a nutshell, these are the kind of people we don't want:

. above all, people who exhibit that peculiar combination of low intelligence and violence that is absolutely toxic to civilized life; and

.beyond that, those who cannot or will not avoid becoming welfare recipients and criminals. Such people share a common characteristic: They are parasites, living off the productive people. We don't need them.

And the kind of people we do want? Why, those who are civilized, educated, and responsible, of course.
