Well, I think we could close it on this note. There are still many loopholes when it comes the law and the constitution, even in other countries.

As for atheism, I think we can say that it's being faithless. But I have faith in having faith and in the believers. Somehow, it's impossible to even conceive the idea of the earth having no religion. Promotion of atheism would be futile. I think the person is smart, as opposed to a mass of people caught in the flow. But as you said, misguided. Many of them are. Most of the time, it would just take one person to preach otherwise and start a following, e.g. Jesus.

As for the holiday signs and other symbols of religion, I think minorities should understand that on of the footholds in building US was also Christianity. I mean, what would be the point in banning signs? If it's not about them, they should not be affected. They have the courtesy of having religious establishments of their own. As I said, live and let live.
