Do you see a lot of Americans complaining about the use of the N-word on the opposite side of the world? I don't think I have ever witnessed that subject come up.
Why would you presume that an American author talking to an audience in America is discussing worldwide social norms rather than American ones?
And I can assure you Ta-Nehisi Coates has spent plenty of time discussing most, if not all, of the alternate subjects you suggested. I'm sure it would dwarf the amount of time he has spent discussing the N-word by a huge margin.
