That's a false choice. One of the rights that we have in the US is to observe whatever religion we choose or to choose to not be religious. The right of religious freedom needs to be defended, including the attacks on religious freedom by the evangelical right. They are certainly capable of defending what they think are their rights. And they are entitled to their day in court. I'm not not completely passive on this subject however -- the next presidential election will some day decide which wing will prevail in the supreme court on just such a subject. And I want my person in office when the next supreme court nomination takes place.
Actually, in the US, more people today than ever are saying they are not part of an organized religion. The trend is against the bible thumpers. Still, about 26% of the population say they are evangelical christian and almost half the country say they are either evangelical or catholic, so the numbers can be against us. Its a good thing many Catholics vote their conscience rather than what the pope says.
As one of the tiny slice of people that would say they are Atheist, I think its probably better to just keep talking with the observant and find common ground where it exists.
