KILLEEN, Texas – Patterson Middle School staffer Dedra Shannon wanted students to know the true meaning of Christmas, so she decorated her door with “A Charlie Brown Christmas” theme, complete with the iconic Bible passage from Brown’s buddy Linus.

“For unto you is born this day in the city of David a savior which is Christ the Lord,” the quote on the door read. “That’s what Christmas is all about, Charlie Brown.”

But two days after Shannon decorated the door with the passage, a scrawny Christmas tree, and Linus waiving at students, the school’s principal insisted she take it down. The school’s focus on tolerance and acceptance doesn’t tolerate any Christian religious reference, Shannon told Fox News’s Todd Starnes.

“She said, ‘please don’t hate me, but unfortunately you’re going to have to take your poster down,” Shannon said. “I’m disappointed. It is a slap in the face of Christianity.”

The principal told Shannon that Linus and his crappy Christmas tree could stay, but the Bible verse was a violation of the U.S. Constitution.

“She said my poster is an issue of separation of church and state,” Shannon told Starnes. “She said the poster had to come down because it might offend kids from other religions or those who do not have a religion.”

“I just took the entire thing down,” she added. “I wasn’t going to leave Linus and the Christmas tree without having the dialogue. That’s the whole point of why it was put up.”

The hypocrisy of the school’s double standard for diversity is glaring, Shannon said.

“Throughout the school there are talks about diversity. Well, you aren’t being very diverse if you are not allowing the Christians to up something up that refers to a Christian holiday,” she said.

Her father, a pastor at Soldiers of the Cross Cowboy Fellowship, wholeheartedly agrees with Shannon’s perspective.

“People want us to be tolerant for everything – but they don’t tolerate Christianity,” pastor Danny Brey said. “They bow down to everything else – but when it comes to Christianity …”

The incident follows a similar situation in Kentucky’s Johnson County Schools last year.

Superintendent Thomas Slayer banned students from reciting the monologue during their production of “A Charlie Brown Christmas” at W.R. Castle Elementary School because he alleged it would have violated the constitution, EAGnews reports.

Parents didn’t take kindly to the change, and when students reached the controversial monologue in their play – when Charlie Brown questions whether anyone really knows the meaning of Christmas anymore – they were ready and waiting to fill in the blanks.

Virtually all of the folks in attendance read aloud Luke 2:8-14.

“The parents in the bleachers basically quoted the verse from the book of Luke, and it was just an amazing moment – it really was,” parent Joey Collins told Fox & Friends. “Everyone was pretty much in tears and clapping. It was just a great time.”
