I never have liked that phrase. It seems to me lately that I see it more and more. Unfortunately those people who seem to use it are on a self-destructive path. When they are cornered or confronted they lash out blast you with the “mindya”. As if that justifies their behavior. If you live a life that is glorifying to Christ and is respectable then you should not be scared of people knowing your secrets or offering their opinions or concerns.
Ultimately it is a lame defense and screams of a deeper problem.
