I'm starting to feel like the "Broken Record" that JG accused me of being.
I cannot speak for others with respect to their reasons, but for me.....
It is not about being offended by Christmas displays, decorations, music, etc. in government facilities.
It's about the idea that such things do not belong in government buildings, since it may give the appearance that a particular religion is being sanctioned or promoted by the government.
And, yes. Christmas has become, sadly, a "non-religious" holiday to a certain extent.
I have no problem with a wreath that symbolizes the "Holiday Season", but I do object to a nativity scene, because it is a religious decoration, not a holiday "seasonal" one.
And Rudolf The Red Nosed Reindeer is about as non-religious a song as you can find, and I have no problem with it.
But making kids in a public school glee club or choir or band sing or play songs like Silent Night or Little Drummer Boy, which are clearly religious in nature, is another matter.
Again, in case anyone missed my POV, looking at a nativity scene or listening to relgious Christmas music in no way offends me.
But this religious stuff doesn't belong in government facilities because it gives the appearance that, whatever the religion involved, it is being promoted by the government.
