At my children’s school around Christmas, outside speakers have come in to teach about Hanukkah and Kwanzaa. Does the school have to give equal time to another speaker who might want to discuss why Christians celebrate Christmas?
The school probably does not have to give equal time for other outside speakers. But if the school is bringing speakers in to discuss holidays in December, it makes educational sense to include Christmas. All outside speakers should follow First Amendment guidelines for teaching about the holidays.
