Khandro - "... Empty vessels is in quotation marks and refers to how such a boy would be perceived by Islamists. I have not said, nor implied that all atheists are empty vessels..."
OK. I concede that.
However, that still doesn't address my central point. You've stated that, "... I have searched the web and can find no examples of real Christians, of any variety, Hindus, Buddists, Jews, Taoists or followers of any religion having become jihadists...".
I have already given you one: Samantha Lewthwaite. There are many others but 'proving' they've become jihadists is obviously rather difficult. Most jihadists, by their nature, are violent, cowardly thugs who like their hide their real identities by wearing masks. They are rather like the quintessential school bullies - pathetically weak when seriously challenged and deeply insecure nobodies who crave attention and 'respect' while showing zero respect to the people they're victimising.
However, by claiming that no 'real' Christian/Hindu/Buddhist/Jew/Taoists, etc. have converted to Islam and gone on to become jihadists, you're using the same two logical fallacies that Keyplus uses regularly - the argument from personal incredulity and 'begging the question'.
