You have obviously never read or listened to the intellectual giant that was Christopher Hitchens. If you have not heard his scathing and insightful attacks on theism you should check out some of his online debates.
I love watching his debates with religious apologists. And I respect the fact that the people who debate him are not claiming 'offense' at the drop of a hat at everything he says. They debate. Unlike a lot of the faint hearted here who want to preach unchallenged. I have a lot of respect for speakers like Danesh D'souza (a christian apologist) because of his debating skill. I rarely agree with what he says, but I respect the fact that he is willing to debate his beliefs and ideas, and not whinge about manners.
I find it fascinating that people who demand respect for their beliefs and manners....do not respect others rights to speak how they wish and want to control them and label them as arrogant, bigots etc and want to control what they say, and how they say it. And yet, the people who speak as they wish and challenge ideas would defend your right to preach.
The irony!
