Sounds like she's in denial. Does she also change the subject when losing an argument?
Anyways, I think you have better chances addressing her denialism than to argue any other political point. As long as someone won't argue in good faith, all other arguements and debates become pointless diversions.
Thank you. It boggles my mind how people seem so oblivious to this problematic phrasing and how unnecessarily divisive it is. I wish these words could be plastered across the internet.
