Same reason why Christmas and Nativity displays are banned and only “Frosty the Snowman” and “Jingle Bells” are permitted to be sung in schools at that time of the year, along with other untold numbers of examples. But Muslim boys as young as third grade can refuse to obey female teachers at school because they are taught that women are always subservient to males, even to boys that age, etc, etc. It really is the liberal hatred of what was long regarded as mainstream and accepted and respected as tenets of our society and heritage.
Every Muslim needs to be kicked out of the USA NOW.
