Have you ever felt bitter towards a race of people and found out that you were from a mix past of that race?

I still have some bitterness towards white people due to some bad experiences from the past. I know its wrong and am trying to change but its hard to unprogram all the crap you've been through. Life has a way of shaping your perspective as a child whether for good or bad. any ways i just found out that my great grandmother was french. this felt really weird to me because im stil struggling with my bitterness only to find out that i come from a white back ground. any one else went through something similar? details please.
