Um. First you criticize "blacks" who may have been offended and say "they should really learn to get rid of that self entitlement issue they have." Next, when that absurdity is challenged, you claim it is merely "(white) liberals getting offended for black people" when no one is actually offended.
Given your express approval of racist sentiments in the past, it is not surprising you are not offended by the ad. When you figure out a coherent (although unreasonable) argument for why no one could be offended, get back to us.
