I can only mention why I want separation of church and state, but here goes.

The Constitution guarantees there's supposed to be no collusion of church and state in the beginning because they feared it would lead as it had in England/europe in general where the church played a huge part in the policies and governance of the people. The founding fathers (several of whom held very atheistic views of religion) wanted the governance of the people to be BY the people and without influence from ANY church.

Any time the government shows favor or preference to any church it opens itself to claims of religious discrimination, and rightfully so, so again the idea was to keep the 2 ideologies totally separated.

These all sound like good and proper logic so the question I always have to ask is why isn't that acceptable to "people of faith"? So long as no one is disallowed from worshiping their chosen deity, why is it that people of faith have to carry that one step beyond and expect non-believers to have to publicly listen to their prayers, pledge allegiance to "one nation under god", or feel as if we must agree with the idea of having "in god we trust" on every piece of currency in circulation?

To me the answer is really simple. It 's because they feel as if atheists HAVE NO RIGHTS simply because we have no religion and could never perceive that we should have any right to even TAKE offense to these displays and practices as blatant examples of the lack of separation of church and state
