Illegal aliens have no stake in that tradition, having rejected the authority and legitimacy of the United States through the act of penetrating the border.
Upon arrival, they are romanced by powerful racial interests, and encouraged to see themselves as “dual citizens” at best. In the shadowy precincts where they live and work, they are treated with contempt, or irritation provoked by the language barrier. It’s understandable that these feelings become mutual.
The illegal immigrant community is a machine designed to manufacture inhabitants, not citizens.
