I am a white christian born in the 60s.  I never owned a slave.  I never discriminated against anyone.  I have never systematically abused anyone, degraded anyone, or stripped anyone of their dignity.  I have never caused any of your problems.  I am not responsible for what someone did long before I was born.

Are you suggesting that white christians have a collective responsibility for actions committed by others?  If so, isn't that racist?
