Because I Said So

AITOOW thinks that if you insert "because" in place of "if" you have the appropriate response to all those sorts of arguments? IE - If A does X then why should we do Y. BECAUSE A does X we should do Y. Real world example from a response in USA Today about Plan B - "Teens are having sex without parental consent, so WHY shouldn't they buy the pill without it? Because Teens (Y) are having sex (X) without parental consent AND SHOULDN'T (matter of opinion), they shouldn't be able to buy the pill without it too. I'm not saying I agree with the counter argument, but, it is a nice rhetorical trick.
