So who gets to be the arbiter of exactly what is appropriate for K-3 students? And what happens when they begin to ask questions that are outside the guidelines set by the state? These kids are a lot smarter than what so called conservatives give them credit for. Many of them know other kids from same parent families. That aside, hearing anecdotes from a niece who has taught K-3 in a rural, extremely poor county here in Virginia for the last 15 years, she has to answer questions that weren't in her teaching curriculum. She's also had to deal with first graders who decided it was a good idea to play doctor during recess. (Try keeping track of 20 kids at once on a playground)
All this law does is cause more confusion and political separation because parents are too lazy or not knowledgeable to do their job properly.
