“Libertarianism is an unpopular view. And it takes particular personality types to be open to taking unpopular views,” explains Kevin Vallier, an associate professor of philosophy at Bowling Green State University, who writes for the blog Bleeding Heart Libertarians. “Some of these personality types are people who are open to new experience, love the world of ideas and have a disposition for independent thought. However, some of these personality types simply enjoy holding outrageous and provocative views, who like to argue and fight with others, who like insult and… shock.” Vallier continued, “The worst flaw in the contrarian trap is that it makes libertarians open to views that deserve to be unpopular and despised, including the thinly-veiled racism of the sort Hans Hermann Hoppe trades in from time to time.” (Note: Some see Hoppe’s support of what he calls a “pro-European immigration bias” as an example of “thinly-veiled racism.”)
