Glenn Beck recently had David Barton on his show for an hour-long discussion. Barton is widely known for his anti-gay views.
In the interview, Barton tried to pull some rational gymnastics to justify that the federal government has the right to outlaw homosexuality. According to Barton, the government has an interest in outlawing certain behaviors, but not others.
…the government has always taken stands on behavior that undermine the government itself. And that’s where morality has always …see, consanguinity, the government’s always gotten involved; you can’t marry your brother and sister, you can’t marry your first cousin. So, there’s always been things that protect the moral climate of the society … You always had standards on behavior.
In Barton’s view, the government can outlaw anything, as long as it isn’t something that he feels strongly about in his backwards Christian ethic.
