[[The Bible does say we are to obey those in authority,]]
True- but we can ask something along the lines of “So just to be clear- if anyone says anything to me that i find offensive, and is not work related, I can report them, right? If they bring up the weather or sports, I’m to come to you and report them? Is that what I’m to understand?”
(Not that you will report anyone- but put the question to the boss- see if he’s truly going about this in an non partisan matter-
And if the boss isn’t ‘non-partisan’?
Keep your peace, be humble, don’t give offense, and prepare for a job change. That’s the right thing to do.
