Here's an NPR Story titled "A Bitter Rift Divides Atheists." The title strikes me as overblown, but there is tension between your Christopher Hitchens (Religion is "sinister, dangerous and ridiculous. . . . I think religion should be treated with ridicule, hatred and contempt, and I claim that right") types, and people who think that kind of rhetoric accomplishes nothing.
I have personally never seen that anything is gained by insulting people. To me the way to advance reason in public life is to live justly and morally while being honest about what I believe. Most people who hate atheism don't do so because they are afraid of secular ideas, they do so because they believe atheism leads inevitably to immorality. Screaming at them won't change their minds. Insults are not arguments, they just make the world a meaner, less friendly place.
