Well..

What it comes down to is what they mean when they say "children aren't emotionally ready for sex". You have to take into consideration the types of people that are generally saying these things. They are used to their adult world where sex is used more for manipulation and as a weapon than it is just as a way to enjoy something with another person. The majority of them grew up without any real knowledge or experience with sexuality, and they were completely unprepared to deal with the sudden reality of adult sexuality when they encountered it.

These same people are also incapable of acknowledging the sexuality natural to children, and as such are unable to understand what sexuality is to a child. They can not see that there is a difference between their own sexuality and that of children, and since they view us as nothing more than adults (albeit, depraved, sick ones) they are incapable of conceiving that we might view sexuality the same way that the children do. In the end, it comes down to the fact that their own view of sexuality is unhealthy and they are disturbed by a healthy view of it in anyone else, especially children.

Unfortunately, those with unhealthy views of sexuality exist even without our community here, and it complicates things all the more. I do not mean to insult or offend anyone, but it does truly concern me what being close to even pedophiles with that unhealthy view of sexuality would do. I fear that what we end up with is children who grow up to be healthy and well balanced adults... until they get sexually involved with another individual and it all turns to chaos.
