At that point a parent should be made aware of that situation. They can deal with it. It’s up to the teacher on how to handle that. But it shouldn’t be encouraged or exorbitantly celebrated in a way that promotes or encourages it. That’s where the problem lies. There are bad apples that actively promote and encourage it. That’s not in any child’s best interest at that young of an age.
I guess I'm dense. Where is the sex? Two men or two women together doesn't constitute sex. It constitutes two individuals together but you're drawing a conclusion of sex. What's the "situation", a child dealing with life? Doesn't that create a "situation", a child and his parents being singled out, ostracized? Do you think the child wouldn't understand that? They know. It guarantees the child's fears. The child can't trust adults.
Doesn't seem much like "freedom" to me either, especially with legal vigilante parents that have already shown a tendency towards violence. It also seems a bit unconstitutional but who decides, vigilante parents?
I don't think this thing has been thought through very well in legal or real-life terms.
