Long story short, we were at a family gathering. MIL got a bit drunk, and then she was generally being nasty. She voted leave, and she was taking the piss out of remain voters. Calling us the n word and stuff. MIL then asked what I voted (remain) and I told her I voted leave so as not to make the situation worse (MIL would have then directed the abuse towards me) DH thinks I shouldnt lie to his mum. AIBU?
