"Nearly all American politicians in both major parties support some limits on legal immigration, and some measures to enforce those laws. Virtually all of them define 'some human beings as "unworthy of legal standing"'—a position Baer insists does not deserve to be defended in public at all. Perfectly cogent arguments can and have been made that, say, Hillary Clinton advocates systemically racist policies or that Bernie Sanders encourages sexism. The ability to associate disagreeable ideas with the oppressor, and to quash free speech or other political rights in the name of justice for the oppressed, is a power without any clear limiting principle. Historically, states that rule on that basis tend to push that power to its farthest possible limit."
