And how long do you need that as crutch or an excuse for a set of failings?
For example the very act of slavery is named after my people, the SLAVS - who a very very white.. On whom do I blame my failiures?
Slavery is larely irrelevant now, the last slaves died a long time ago.
The only historic thing that matters is that blacks have only had full civil rights for some 40 years. The way to move forward from that is to focus on the future, and not ***** about the past.
You can ask anyone to forget, but you must ask people to forgive and focus on the future...
