This will become a tedious argument if you insist on relying on examples of individuals. I can come up with a Christian for every Atheist you dredge up.
For every Stalin, I'll point to a Christian Hitler.
For every Mao, I'll point to a Constantine (first Christian Emperor of Rome who purged the empire, family too, in much the same way Mao did.
For every egotistical Carl Sagan, I'll point to a Jimmy Swaggert who's ego was so large that he could preach against sin every day and meet with his prostitute every night.
I guarantee you that as a group both Atheists and Christians have geniuses and idiots, saints and sinners, good Samaritans and jerks.
Of course there are egotistical Atheists!! Of course there are egotistical Christians!! The personalities of the individuals are similar because they all come from the same population called mankind.
The argument is not about the individuals but about the theology.
Hitler was not a Christian. He hated Christianiy. He sought to destroy Christianity. This has been established to the point it can't be disputed.
That actually sounds like some people on these forums.
This is a bit much, Doc. The Christians I know don't kill 6 million Jews. How can you possibly expect to be taken seriously with an argument such as this?
How about we go the other way? If I show you a Mother Teresa, who do you show me? How about William Wilburforce (the man in British Parliament most associated with the outlawing of the slave trade)? William Booth, founder of the Salvation Army, which is still tirelessly living by the motto "Soup, Soap and Salvation" after over one hundred years? Or John Fletcher, Vicar of Madeley, who was Voltaire's answer to a fellow skeptic's question, "Have you ever met anyone that was like Christ?" and was so concerned for the poor that he cried "My poor! O, who will care for my poor?" on his deathbed?
Who would the atheist point to as his highest example of living?
