We are atheists and find religion in school to be offensive and uncomfortable. The school isn't terribly bad, but stuff does creep in here and there, mostly associate with holidays.
Where I think it's most obvious to me is for my dd who is in chorus. Now, I understand that much great music has religious origins. The classical stuff doesn't bother me, but the cheesy hymns, complete with lyrics praising Jesus does bother me.
Yep, could have written that post.
Also, the santa thing bugs us a lot because they try to get away with that, too... saying its more secular than sacred but you know.. that holiday/holy day has a big Christ at the beginning of it.
