We often hear Christians say that a prayer or religious symbol at a US government function is fine and that atheists shouldn't complain. But is this the pot calling the kettle black?
How many of those Christians that complain that their religious freedoms are being stepped upon when it is asked that the separation between church and state be upheld would stand by if an adhan was done in their town? Hell many Christians freak out if there is a proposal for a mosque to be built any where near by.
The separations of church and state is there for a reason. So that no American feels undo pressure, about their religious beliefs or lack there of, from the government.
So if you are one of those people that think that atheists are the problem ask yourself "would you mind at the same time as your "state sponsored prayer" that a Muslim call to prayer be held, then a Hindu mantras, then a Buddhist chant, then a Wiccan ceremony...." The list goes on. You don't have to join in. Just look away when the high priestess and priest have sexual intercourse to invoke their gods powers.
To often people think it is ok because it is their world view but soon forget the "tolerance" they expect of others when it is someone else's world view that is asked to be publicly displayed. Forget about being promoted by some government official in their official government capacity.
