A high school teacher claims she was forced to remove a Hello Kitty Christmas tree from her classroom.

Catherine Gordon, a math teacher at Bangor High School in Maine, wrote on her Facebook page that "everything offends everyone all the time" and that it "just sucks the joy out of everything." This comes after she was allegedly ordered to take the pink Hello Kitty-themed tree out of her classroom.

The school superintendent said in a statement that culture, traditions, and holidays must have an educational component and must be tied to the curriculum.
