No amount of apologizing is going to unring that bell.
Right, so I wouldn’t bother to grovel.
Not if you're black, for sure.
As Jesse Jackass has often said, if you are contrite and sincere, the American people are obligated to forgive you (e.g. Willie, Monica) but that only applies to Blacks Or people they endorse.
Specially whites need not apply.
You aren't kidding. Not even 600,000 fatalities in a horrific civil war plus hundreds of billions in transfer payments in the intervening time could unring that bell.
