I understand your point but remember that changing at 80 or even 60, is crazy hard, especially when you were raised on something. Perception is reality and their reality was racism. by this time, they've been there done that and feel its their right to think and behave how they want. It's not right and I agree with you that it's awful and racist but you just have to ignore it and try to help teach the young to think differently by showing them that all people are equal as humans. You can't waste your energy on someone who doesn't want to change.

I do think you had every right to say something though, if it makes you uncomfortable. Your comfort and happiness is just as important as anyone else's.
