Bizarre defence, and it gets worse. She goes round saying or liking horrible things about all sorts of people and can't remember or excuses all of it.
I'm not sure it should work but surely she should be able to realise her best line of defence is simply "sorry", without any excuses and acknowledging the offence. I don't understand why her social media accounts haven't been checked before selection, either. If they were and this is the least offensive, I think the failing candidates accounts deserve attention
