Yes, we've been over this. It's wrong and unfortunate that people of color have been targeted (violently or not) and insulted in the past and now. Those insults are false. They're lies, propagated by racist liars.
Countless other cultures (gauls, germanics, norse, turks, mongols, etc) have been similarly characterized in the past. We've moved on.
I believe no present day french, german, swedish, turkish or mongolian person would feel offended by the D&D depiction of orcs, even though their ancestors were characterized in a similar way. In time, that will be true for people of color, as well.
