And the black kid not a good American?
I have no way of knowing the answer to that question. You may get a better understanding of what I meant by reading the rest of the post.
The point was that this kid reacted to a threat against his race in a different manner than patriots react to threats of those who act to damage their country. The kid's inclusion in the first example doesn't exclude him from being a member of the comparison group of the second example.
He may be a good American. We don't know that for sure.
