SI, I'm a veteran (an atheist in a foxhole, then, as it were, and today I carry a slight disability due to my service), I'm currently a trusted civil servant in a position of some prominence, and I pay taxes, support my government (and serve as loyal opposition when necessary -- a lot lately), volunteer in the community, act as a voice of conscience to many for whom I have some influence, and I maintain that I am a citizen and and good one. And I am an atheist. And further, I take personal umbrage with your baseless assertion that an atheist cannot be a good citizen.
I call foul and say that your assertion is a lie and further assert my own self that you, then are knowingly perpetuating a lie and are your own self thus a bad citizen.
Please, come visit me someday and call me a bad citizen to my face. I'd love to discuss it in person with you ...
I'll buy the beer.
