Vampires respect others in ways atheists do not. Vampires at least have some reason to fear Christian symbology because it causes them some harm. Whereas, the"harm" alleged by atheists is a figment of their imagination.
There was some atheist group complaining about the cross at the 9/11 memorial because seeing it gave them 'headaches.'
It seems like just about every day another story crops up about atheists attacking another place where they found a cross. The one that set me off this morning was where a woman had put up a cross at the location where her son was killed in an auto accident. I don't know about where you live, but such "memorials" are frequently erected at such roadside locations. This group of atheists had their tender feelings mortally wounded because some woman wanted to honor her dead son and her cross was on a public right-of-way. C'mon, really?
While they may argue that their 1st Amendment rights under the establishment clause, the phrasing is quite open to debate due to differences in interpretation.
The 1st "Prohibits the making of any law respecting an establishment of religion, impeding the free exercise of religion, abridging the freedom of speech, infringing on the freedom of the press, interfering with the right to peaceably assemble or prohibiting the petitioning for a governmental redress of grievances." You could just as easily argue the second portion saying the the "free exercise of religion" is being impeded by their demands that any religious symbol they find offensive be expunged from public view.
I will continue to ask, if atheists recognize no god(s), why are they so offended by some symbol that should have no meaning for them to the point of trampling on someone else's Constitutional rights, if needs be to satisfy their vitriolic hatred of such displays?
