Apparently WWI was a religious war. I did not know that. I fault my public education.
Here, one Latin cross in the desert evokes far more than religion. It evokes thousands of small crosses in foreign fields marking the graves of Americans who fell in battles, battles whose tragedies are compounded if the fallen are forgotten.
Bullshit. The cross at issue is sections of white metal pipe stuck in the ground in a park the middle of nowhere. Hell, the cross that's standing now isn't even the original, so a "historical structure" argument doesn't even have merit. There are WWI memorials all over the world, there is a national day of remembrance, and the war is still taught in schools. The soldiers are collectively not in any danger of being forgotten, and absolutely nothing prevents any American from erecting a WWI memorial with a cross on their private property.
But that's not good enough for Christian theocrats.
Lest you think I'm being unfair to Christians, it's worth noting that park officials previously rejected a proposal to locate a Buddhist shrine near the cross.
