I am a bit concerned with Mrs. Rickman's attitude. Yes, she is your child, and it is good you want to protect her. But insisting she is your child as if you own her or you alone should make choices for her, seems very self centered.
It makes it seem if you are less concerned with her well being, and more concerned about what you think.
I don't agree with with this promotion. I don't condone what the company did. I don't consider this particular clip pornography to me, personally. The definition of that word is to entice arousement. Barring a very niche selection of people, this is not arousing. I guess it's defined, as such, regardless, but I don't object to pornography, and don't think anyone should. I only object to its de-evolution into fast and cheap sex. Sex is beautiful, and there is some porn out there that is loving, but sadly that's rare. I don't want it to be grouped into the word pornography, and certainly not films of this extreme nature.
Technicalities aside, I guess what I'm saying is, I'm concerned you want to shelter your child completely from sexuality, when that's a recipe for disaster, and what I would call bad parenting. I suggest you be open and casual about sex, and teach your children about responsibility and consequences.
I don't want your children having unprotected sex because you felt everything would be okay by not talking about it, or thinking you could sweep it under the carpet and make it go away. Sex isn't something that is taught. It's a natural instinct. They will engage in it whether or you like it or not, so I hope you're honest about it to them.
And that includes talking about films such as this, which can be done respectfully to both quench their curiosity and help them make better choices in life.
Sit her down, don't be angry, and tell her, "Recently you may know mom got into a panic over something called 2 girls, 1 cup. It's all over the news and such. I shouldn't have gotten into a hissy fit. I over-reacted. I should have just sat down and talked to you about it, instead of making a big deal. By making a big deal of it, I probably backfired everything by giving it more attention.
I was concerned for you. I didn't want you watching something like that. Such material goes out of the bounds of what is acceptable for someone as modest as us. It's not something that will make you feel good to see. I'd rather say it would make you feel very sick. If curiosity still gets the best of you, I can't stop you from watching it somewhere. But if you do, I want you to come talk to me about it. I want to know what you thought. If you felt sick, maybe it's a lesson to be learned that your mom isn't as dumb as you think. If you are un-phased, which I'd highly doubt, maybe you are more mature then I thought, and can handle things in a mature way. I could possibly even take a note from you.
I can only be a parent to you, but not everyone. I can't babysit the world, and I can't make choices for other families. Your mom loves you and wants to be a part of your life to help you grow. She also wants to make sure you can have the happiest and healthiest lifestyle you can until you get on your own, while still letting you be you. I don't want to impose on your life, but I do want you to impose on mine.
If you ever need to talk about something, please don't be shy. I know you may feel embarrassed or hard pressed to talk to me, but you don't have to be. If you need me, I'll be here."
