So Tim, you want to explain how those things aren't related?
It is indeed, at least partially, about how we treat each other. Unless you are a total fanatic--as Mr. Cook now appears to be;--you understand & respect the fact that other people want the same right that free men & women have always had; and that is right to decide for themselves with whom they will associate; with whom they will elect to do business; with just what they will choose to identify, and just what they will seek to avoid.
Tim Cook has now distanced himself, pretty clearly, from those of us who believe that we should treat others with respect. As he rejects that concept--and he has here very clearly rejected that concept--we reject him. (Frankly, he strikes one as a bully in the Ernst Roehm mold.)
