I'm very sorry that some people just can't tolerate the differences in people and don't really understand that the USA is supposed to stand for justice for _all_. The tax money of athiests, jews, muslims, buddhists, et al paid for that rock. A rock which has nothing to do with their beliefs and in some cases it's symbology goes right against it.
Many (most?) christians are perfectly happy acknowledging that different people believe different things and don't feel the need to have their belief scrawled over everything or forced upon people who don't want it. Unfortunately people are always characterised by their worst representatives, so now when most people think about christians they think of biggoted assholes who won't stop until everyone is christian.
Something else which seriously bothers me is the persecution complex. Just because people complain that this stone is there, many vocal christians jump up and scream "Hey, you're unfairly targeting us as christians and trying to force us to stop practicing our religion!"
No. You aren't being persecuted. They only reason why you were singled out is because you're violating the law. Maybe other christians aren't violating the law and they're left alone.
Just to make things clear, I am agnostic and most certainly not a christian. I respect other's beliefs and would defend their right to belive and practice whatever they want, just as long as it isn't pressed upon me and I am not required to fund or partake in their religion.
