I ask again...You're not opposed to injustice, as long as it's committed against someone else. You can't bring yourself to condemn black people who commit an injustice.
Are you upset, at all, about the systematic injustice inflicted upon black Americans now, and since they've been in this country?
Why would I be upset upset about history that I had nothing to do with? Furthermore there is no systematic racism against blacks today. Only a fool would argue otherwise.
