Even as an agnostic, I am not willing to demonize the 70.6% of the citizens of the United States who identify as Christians.  

The agnostics and athiests total 7.1% of the population.    Even if  they are all sainted cognoscenti and even if there were enough of them to hold all the political offices in the country, they are still  impotent without the other 92.9% of the population.  

In other words, get over yourself.
