My Letter to Jerry Falwell, Jr., and Liberty University …

Here.
A quote from the letter:

Your message faithfully represents a longstanding (and ugly) stream of American culture and politics. This tradition goes back to those who argued against the equal human rights and dignity of the Native Peoples and African-American slaves, often abusing the Bible to justify white supremacy under its various guises.
It was also manifest in the Protestant prejudice against Catholic immigrants, in centuries of morally repugnant anti-Semitism, and in the unethical treatment of the Japanese during World War II. During the McCarthy era, it launched witch hunts using “red” and “Communist” as its epithets.
In this ugly American tradition, your father used antipathy towards gay people to rally his base, and now, you are doing the same with Muslims. You are being deeply faithful to a tradition that is deeply unfaithful to the life and teaching of Jesus… not to mention the broader American ideal that upholds the dignity and equality of all people, whatever their religion.
