"Sex should not be discussed in an elementary school. "
We agreed on that. They aren't discussing sex. Heather has two mommies is not about sex.
Whatever diseases you did or did not get (I've never had any either, nor been pregnant, and I'm 25) doesn't prove anything about social engineering.
"Heather has two Mommies" is a lie....that Heather can actually have two mothers is a biological lie to be specific.
Not even touching upon the moral fact that a child deserves to have both a mother and father to grow up in an optimal environment since the world consists of both men and women.
Lies confuse children and that is why truth should be the focus at any school.
