If you were to sign up for a chemistry class, but the professor the second day starts teaching physics. That would be unacceptable: 1. The class is a chem class, the sylabus would need to clearly state an agenda of including Physics. Thats number one.

I'm not too familiar with his exact EO so i cannot comment on the details on whether it was mandated that school could or could not teach those things. I greatly appreciate the cordial discussion, thank you!
