Larry Elder wrote this book over ten years ago. He was (and may still be, I don't know) a Libertarian radio talk show host in southern California at the time. The things he says you can't say, well, some of them have and are being said since that time. So, this book is a little dated, but the arguments he made are still valid and very well executed in the text.
What are the ten things that you could not say in America?
Blacks are more racist than whites.
White condescension is more damaging than white racism.
There is no health-care crisis.
We are losing the war on drugs.
Republicans and Democrats are the same beast with different rhetoric.
Gun control advocates have blood on their hands.
Illegitimacy is America's greatest problem.
The welfare state is our national narcotic.
There is no glass ceiling.
There is a real, widespread and destructive left wing media bias.
He made good arguments for each of his points. Granted, they are Libertarian arguments and therefore will blame a lot on government. I don't disagree with him in a lot of those areas.
This was an interesting book that would have been far more interesting ten years ago. Although, at that time I may have looked at it as more of a fringe wacko type book than something more mainstream that it has become today. Libertarians have come a long way since then.
