I had a pastor once who when he was in his prime had a buddy that he use to debate different concepts of doctrine. He said that they would switch back and forth on a doctrine and found that they could both back up and argue doctrines from two different views by cherry picking scripture to back them up.
My husband can debate both sides of pretty much any subject, whether he believes in it or not. He has argued both sides of gun control for the fun of it. I remember in college writing a paper stating why gays should be allowed in the military. I was actually proud of that paper but never found out my score on that particular paper. (I didn’t do well in that English class, in general)
