In "The World According to Bret", we learn that this is a complex world - one where millions of lines wouldn't suffice to deal with the complexity of race in America, for example.
I believe the world is indeed very complex, though race in America doesn't look to be particularly so.
With races, it is all very simple: we have genes, and some have superior genes, while others don't. I've learned it with The President of the United States of America, so it must be right:
"You have good genes, you know that, right? You have good genes. A lot of it is about the genes, isn't it, don't you believe? The racehorse theory. You think we're so different? You have good genes in Minnesota."
How could Bret disagree?
