Maybe you should read this book. I haven't, but I know that even us innocent ones have unwittingly had advantage of systemic racism that made it easier - or less hard - for our ancestors to go forward in the world. We don't have to be ashamed of that as such ... unless we deny the gross injustices that has benefitted some a lot, others a little, and some people not at all. If we keep being offended when someone points out those facts, then we actually do have something to be ashamed of.
