MIL has said a few abhorrent racist things in the past. Yesterday's gems were that "blacks" don't know how to cook properly and litter the streets; and that immigrants ("blacks and Eastern European gyppos") cause the majority of crimes in Britain. She always says "we think" as she speaks for FIL.
She's mid-seventies, has lived in Worcestershire all of her life; and her DC say that she's just too old to change and that most elderly people are racist. They and the grandchildren are definitely not racist.
I just don't buy that. Age isn't an excuse. But AIBU?
