It's jerkoffs like you that have completely given up on morality and your duty as a parent to protect your kids that propagate this problem to the point it is now accepted as the norm!.. Disgusting! And the fact that we've become so socially numb to it all is saddening.. you my friend are a shining example..
I'm not a parent yet, so maybe my views will change in a few years, but I've always thought that when I do have kids, my duty is as much to educate them and prepare them for the world as it is to protect them. And your use of the word "protect" seems odd to me in this context; we're not talking about someone attacking your children, we're talking about them being exposed to a verbal depiction of kinky foreplay and sex. Is it really "protection" to shield them from depictions of acts that make you uncomfortable? Again, I'm not a parent, but if I were confronted with a similar situation, I would hope my response would not be "YOU SHALT NOT READ THINE SMUT," but rather educating my son/daughter that such depictions are descriptive of acts that I personally find immoral. If I've done my job educating them up to that point, they should be able to understand that they might be exposed to things they, or I, don't agree with in the context of their education, and that's OK.
Have fun being a 35YO Grandpa raising a baby again after your teenage daughter gets knocked up because they read this book and thought it would be a good idea to try. Wish HER luck for me making it through high-school and let alone college and on to a productive adult live. Not that it can't be done - but it's gonna be about 100x tougher.
This would be physically impossible without adoption being involved. Even if I started right now, my daughter would have to get knocked up at age 3 to make this happen, and that's very unlikely; I'll be sure to teach her about contraception.
But ha.. fuck it, no reason to get be concerned about my kid's education.. Too easy just to look the other way. I'm a relic.. blah blah..
I don't think you're a relic, I think you're misguided in your attempt to shield your children from any depictions of things that make you uncomfortable. Education is about confronting uncomfortable situations, not running from them. If one paragraph is all it takes for your message of "sex is immoral" to be abandoned by your children, you've failed to educate your children as to why you believe that and why they should to. That's not on the school.
