I didn't see anything that indicated that there was any sexual instruction....
I guess we will never know how detailed the instruction was, seeing as how the administration has kept it Top Secret and forbidden the parents from knowing.
And we will never know, will we? A public meeting held in a public building involving minors was not allowed to be recorded by a parent of a student who is an attender of the school. We will never know what went on at that meeting through an objective witness (the camera). Is that acceptable?
