students should learn about social technologies. If not, their safety and reputation are at risk when they try to work these things out for themselves later. It's as important as teaching proper grammar and ensuring they know not to get into cars with strangers.
I'd say it's as important -- if not directly analogous to -- health class.
And something tells me that the next fight in the schools will be over precisely this issue. And it will be led by the same folks who don't want our kids learning about certain things in health class.
