A few of the many..
"Spelling and grammar aren't important!"
"Abortion is murder!"
"You're going to hell for your homosexuality/bisexuality."
"I need guns for self defence."
"My family of 4 people need 8+ cars."
"You should wait until marriage to have sex."
"You should be loyal and obedient to your male spouse."
"[race/sexuality/gender/stereotype] should, without exception, be degraded."
Edit: I'm adding Creationism to the list.
While none of these cause a complete separation between body and brain, they do tend to warrant a fist-to-face reaction if, after several minutes of heated argument, the tactless Burke still clings to them.
