There are differences. But also things in common. Both statements get to "like me" by using skin color (or race) as proxy. And so we learn "people (un)like me" are people of the same color, and now you see they are the same statement.
Adams was condemned, fired, newspapers print his guilt, and the parent of this thread selects a bit of evidence for his guilt: he wanted to self segregate.
As for the Georgians, we condemn them in private equally as Adams. However, because they are black, society lets them be racist.
In any case, what bothers me more is the art not being separate from the artist. If there's merit in Dilbert, I hope someone picks it up.
