I responded by asking which ones.
I await her response.
If my children's classes are involved what I will do is go to the school and provide an alternative lesson - such as one of the principles found in "The 5000 Year Leap".
I'll also consider calling the other parents in the class and let them know what's going on and they can act accordingly.
I guess your district left it up to the schools.
I called my district, and they said that they don’t believe that political or religious speech should be taught in school, so none of the schools in the district will be broadcasting his speech.
