so if the parent does not do their job, the state should?
What do you do when a gov't or school district ignores science and biology and teaches abstinance and not birth control for example.
why do you have the school teaching this subject? we turn out kids that can't read, can't compete in science and math, yet we spend time on birth control and using rubber dams for oral sex. then, because apparently kids are still flunking this class also, we set up a nursery in the school for the moms and carry on.
the job of the public school is to turn out kids that have an education in the sciences and languages. it doesn't do a kid any good to know how to properly perform oral sex, but not know how to read well enough to fill out a job application.
some kids aren't going to get it, but this goes back to teaching to the lowest common denominator. teach up, not down. if there are kids who don't learn, so be it. at least the ones who do want to learn, and who can learn, will have a chance to be successful.
