"By nature, Christianity is a moral religion and highly-respectable. There are just stupid people who try to pervert it into what they want it to be."
"By nature, America is a good country. It's just not perfect. Nothing that is human is perfect."
"By nature, Iraq is a good country. The fact that it was run by a dictator made Iraq a horrible place."
