I'm well aware of history and the fact that people have enslaved and subjugated people all over the globe through out time all the way up to this day. I don't think you need to feel guilty about it. I certainly don't. I'm not going to apologize for the sins of the past. I can recognize them though. If you can't admit there are problems today, due to the racism of today, you're either living in Mayberry, have your blinders on way to tight or your in denial of your own racism.
