Now for my two cents.

Having actually grown up here in the USA as an impressionable non-Christian child, I was always made uncomfortable in school... being forced to pray to Christ. Yes, you don't realize how it is for non-whatever kids it must be to grow up in a secular state. Sure the Constitution said freedom of religion but until recently that wasn't what was practiced.

And Thorne is, imo, quite right. I don't see many non-Christian complaining about Christian practices. Just the more radical "Christians" objecting to those who want non-denominational celebrations. Why... it's as bad as those radical muslims objecting to anyone who uses islamic imagery to make a point. You know... the terrorists. (A concept that goes back to the Reformation. )
