Wanting to show your daughter that you support them and care about them and want to help them follow in the beliefs of your religion - and a belief that is not in the least bit harmful in any way - is a bad thing? Abstinance only education might not work for most people - especially in today's society where the belief that "everyone is bad and is going to do bad things so we might as well help them do it as soon as possible" reigns supreme. But abstinance in and of itself is not harmful to anyone. If anything, it is a good thing because most of those early relationships are going to end quickly anyway and it is a lot less painful if there was no sex involved - you can't feel "used" if you never got used... The kids should be taught both sides so they understand the consequences and know where and how to get protection if they decide to have sex, but that doesn't mean we need to encourage them to do it or discourage them from waiting.
I don't support doing these at such a young age, but if I had a teenage daughter who was entering high school and knew about sex, I wouldn't see a problem with something along those lines. Being in a crowd of people with similar values shows support, and making an event out of it makes it easier to remember. What would you remember most? A short talk in the car on the way home from McDonald's or an event where you dress up, have a nice meal, etc? Doesn't have to be a big public banquet, but making a special occasion out of anything generally has more impact and is better remembered.
So those of you who would prefer we show our high school freshmen porno films at assemblies so that they can "learn the basics" and then send them out to have sex with anyone and everyone can hold to your belief - it is your right as an American. But you also have no basis to assume that any attempt to protect our kids from the negative consequences of sex are always a bad thing and are carried out with evil intentions. And the majority of churches and families these days would not ostracize a young girl for getting pregenant before marriage - just because they don't support the idea doesn't mean they won't support their loved one and help them in any way possible. Love isn't vengeful. It isn't the babies fault. And the parents should be forgiven and helped. Just because a Christian doesn't encourage pre-marital sex and having children out of wedlock doesn't mean that they would be hostile if it happened. That is just a typical liberal lie. It happens, yes, but rarely and generally only in extremely old-fashioned churches. The majority of your mainstream "Evangelical Christians" are much more "friendly" than the liberal agenda would lead you to believe. But how would they know? Contact with holy things like churches tends to make their skin sizzle...
