kerry, experience-based mistrust and prejudice is entirely understandable. However, the problem with that is that it can often lead to complacency in other areas iyswim.
So, based on your experiences, you are mistrusting of men. Therefore, I'd imagine that you do not hold the same mistrust of women. However, women do also abuse children - far more than is believed to be reported. So rather than have a mistrust, it is better to teach children about the ability to tell/say no/what is right and wrong, rather than to assume that any of the individuals they come into contact with are going to abuse them.
Let me try to use a slightly different analagy (sp?)
In recent years there have been a few high-profile dog attacks on young children. Many of these dog attacks have been carried out by staffy-type dogs, or rottweillers. The reason they are so high profile is because of the sheer amount of damage a powerful dog like that can do, often with devastating consequences. As a result of that, there is now a wide-spread belief that staffies and rottweillers are dangerous breeds who should never be allowed anywhere near children. This assumption is based on maybe ten attacks within the past five years. But actually, the breed of dog that bites most children in this country is the golden retriever, a breed that is highly regarded as a fantastic family pet. Retrievers aren't renouned to be vicious; the statistic is based on the fact that there are more retrievers than staffies in family homes. But still your child is more likely to be bitten by a retriever than a staffy.
In the same way, your children are more likely to be abused by a family member than a stranger working in a childcare setting.
We have to teach our children to respect dogs, not to intimidate them and that on the whole, most dogs do not attack unprovoked.
In the same way that most men are honest, trustworthy people who find child abuse just as abhorrent as we do. But we teach our children that if any adult wants them to do anything they don't want to, in terms of interaction with their bodies, they have the right to say no, and to protect themselves.
