How strange....I live in Montgomery county one of the bluest counties in this blue state of Maryland. My daughter is now enrolled in our local public school. Their Holiday celebration and concert, included Christmas carols, secular songs as well as some jewish songs celebrating Channukah. They sell candy cane-grams within the school, that can be sent to teachers and students as a fundraiser. The teachers including jewish and hindu performed a Christmas song for the concert donning Santa hats.
Obviously they haven't gotten the memo...or some states have just gone whacky.
