Because it causes direct personal harm to another or another's property.

Therefore drugs should be legal. As should alcohol. And prostitution. And many, many things that are illegal.

As far as "sex education," beyond the biological facts of sex, I don't really care what schools teach though I think too much time is spent on it regardless of the specific pedagogy. The negative results of sex are generally not the result of stupidity but rather immaturity and you can't really educate children out of that. School should not be about creating "good people." Telling the various facts about sex is not "intruding in our sex lives." Criminalizing certain types of sex or mandating others would be intruding on our sex lives.

If this stops the casino spam from invading my inbox, I'm all for it!:D

Seriously...I'm for education, since we've got the system in place.

Otherwise let's let the kids loose on the streets with no nanny state whatsoever! Complete freedom from State authority! All parents should not work and stay home to teach their kids (hey - that should be your #1 job, you slacker) -- who cares if dad or mom ran off and you can't pay the electric bill. You'd better freaking be there to be the moral authority. Especially if it's in the dark. You don't expect ME to help you out, do you? Lazy layabouts having kids without thinking about any-and-every possible turn of your personal futures...you make me sick.

I'm going to teach my kid about the FSM. ;)
