It most certainly can. Sadly, I fear that rampant revisionism (from both sides) is at the core of the desire of both sides to win this one.

Those on the extreme right wish to maintain their delusion that this is a Christian nation -- on the order of God's promised land/people Israel.

On the other side stand folks who, like many on this site, would like to enhance their ability to revise history to reflect a Christianity that they believe to be the reality -- a barbaric, ignorant, sheep-fucking, redneck Christianity incapable of the genius that founded our constitution. The thought that Christianity would actually be instrumental in the founding of our nation and its constitution (with, ironically, its "no establishment" clause) is not the Christianity they wish to paint for them and theirs and future generations.

Get rid of any outward signs and symbols that refute their view of the Christianity as evil, and a nation founded on anti-religious secularism, and they make great strides toward their brand of revisionism.
