Being targeted by the SPLC has had a lasting impact on my life and career. Offers from other universities ended and speaking opportunities declined. Once you’ve been smeared in this way, mainstream news outlets are less likely to cite you as an expert of any kind.

Yet today I wear the SPLC’s mud as a badge of honor because I know I am in the company of many good men and women who have been similarly vilified for standing for righteousness and truth. Other SPLC targets have included Ben Carson (who eventually received an apology and retraction), Somali refugee Ayaan Hirsi Ali, terrorism expert Steve Emerson, political scientist Guenter Lewy (who successfully sued the SPLC), attorney Robert Muise, Frank Gaffney of the Center for Security Policy, and Princeton professor Robert P. George. The SPLC has tagged Mr. George, a devout Catholic intellectual, as “anti-LGBT.”

Whatever label the SPLC assigns, such smears are harmful and designed to destroy the individual’s credibility and ability to have influence in the public square.
