Abstinence-mostly education?

Wisconsin Gov. Jim Doyle signed a bill yesterday that will require all sex education classes in the state to put an extra-special emphasis on abstinence.
A spokesman for the governor assured that most Wisconsin schools already take that approach. So why make it mandatory? They probably don’t even have orgies in the classrooms until the very end of the term!
It makes enough sense — instead of trying to replace sex education with abstinence-only education, the sex-haters thought they might as well just try to change the actual curriculum of sex ed itself.
Sounds like some kind of faux compromise that’s just going to get worse.
