Sex Eduction for Kindergartners?

Recent news reports about schools in Montana that are considering adopting a sex ed course for early elementary students have been flying around the Internet. This latest on the topic was on FoxNews.com: 

 "According to the 62-page draft proposal, beginning in kindergarten, school nurses will teach students proper terms such as "nipple, breast, penis, scrotum and uterus." Once they are promoted to first grade, children will learn that sexual relations could happen between two men or two women. By the time students are 10 years old, instruction will include the various ways people can have intercourse, be it vaginally, orally or through anal penetration."

I've tried to ignore this story, hoping people would come to their senses and it would just go away, but apparently it isn't going to.  The school superintendent of the Helena school district is pushing for the curriculum, saying that the schools share a responsibility for making sure children are informed about the risks of certain behaviors.

Opponents of the plan sharply criticize the idea of giving such specific details about sexual acts to children as young as ten.

I've got to say I am on their side.

There seems to be no childhood anymore. No time of innocence.  Children are exposed to too much, too soon in regards to sex and sexual activity. If children below the age of 10 were not battered with sexual content and sexual images all around them, maybe their natural curiosity about such things would wait until they were a little older and better able to process the information. 

And this type of detailed sex education belongs in the home, to the parents, who are the best judge of when their child is ready for it.

What do you think?
