What's a phrase you hear a lot, but disagree with?
One that comes to mind for me: "Whatever doesn't kill you makes you stronger" is not always true. Maybe even only half the time!
Are there any phrases you tend to hear and shake your head at?
Most of the time those two words can be correctly replaced with "I believe you to be an irrational eager to swallow any crap smeared on its filthy snout."
(People who deserve your trust typically don't evoke it.)
Because if you need reasons, then you don't trust them. And they can take your refusal to do/believe what you're told to do/believe as a personal attack, you know? It's emotive manipulation.
