I have a lot to say about this very thing and I feel very passionately about it. I think the permissive parents in today's society are the reason why we have so many issues with our young people these days. There is a reason why this game is rated Mature, but a lot of parents simply do not care. I have noticed more and more how permissive some parents are, where as the parents who set the guidelines are the ones who are too strict or overbearing. My DS is 9, he is not allowed to play any games that are not rated E, plain and simple. He begs and complains that so many of his friends have them, but I tell him they are not my children and I can only do what is best for him.
A co-worker and I were talking about the subject of kids today and it is a shame that the child with manners and respect are fewer and far between today. A lot of this stems from permissive parents, absent parents, parents who are too tired or overworked to parent and parents who allow young children access to things (games, TV, movies, etc.) that are inappropriate for their age. It is our responsibility as parents to instill proper values in our children and that is hard to do by allowing young children unlimited access.
{Stepping off my soap box now.}
To (finally) answer your original question, no you are not crazy at all!
