Shhh … don’t talk while I’m feeding!
“What would Jesus do?”
I’ve heard it a gazillion times – the real meaning being, “reconsider your own behaviors and beliefs and do as I want you to do” or “Do as you’ve been told by your [Christian Church] authorities.”
There are many such sayings that appear on the outside to mean what they say but instead carry hidden messages or meanings intended to coerce or to reinforce prior conditioning or to take advantage of common thinking errors (see http://powerstates.com/10-cognitive-thinking-errors).
