Talk about a war on Christmas.

The music teacher at Cherry Knoll Elementary School in Michigan decided to replace the word "gay" in the popular Christmas carol "Deck the Halls" because students were giggling.

"Don we now our gay apparel" is one line in the song, but the teacher changed it to "bright apparel," according to The Chicago Tribune.

Principal Chris Parker immediately reversed the decision when he found out about it.

"This would have been a great opportunity to teach that 'gay' has more than one meaning and is not a bad word," Parker explained to 7&4 News in Traverse City.

"We have an anti-bullying and discrimination policy which includes sexual orientation. So going forward, the teach will be addressing, 'This is how we are supposed to be reacting. This is the way to be respectful about this,'" he added.
