My friend Constantino Diaz-Duran, an immigrant from Guatemala and now a student at Columbia University, offers his views in the Columbia Spectator on the shameful violent shutdown of the “Minuteman forum” at Columbia, and on the benefits to the nation of immigrants, as well as the dangers of welcoming immigrants into the welfare state, rather than productive work. Constantino has written for Cato’s Spanish-language website, www​.elca​to​.org, and was involved in the production of Cato’s bilingual English-Spanish edition of the American Declaration of Independence and the Constitution of the United States.
