Hitchens admits publicly that he writes in an inflammatory tone for the purpose of getting attention and selling books, just like Ann Coulter. You can't read anything more into his "tone" other than that he wants to sell books and get himself on TV shows to promote his book.
1. Louis Farrakhan probably does the same thing. And the KKK often holds demonstrations with a very nasty tone, but don't read anything into it, they're probably just looking to sell books.
2. Dude, if I walk into a crowded airport and yell, "Everyone look over here, I have a bomb" you wouldn't need to read anything into my tone either. Hitchens recently said he wants a war against all believers. I don't care why this dipwad hater says what he says, I care about the fact that this dipwad hater is demonizing most of the human race and attacking a main component of Western civilization while claiming to defend it.
