bballman,
I think the discussion is great. We obviously have different views on the topic. From where I sit, the important aspect is providing parents of 10-12 year olds and those soon to be 10-12 some views on this issue that will cause them to think carefully and take cautions.
Whether they take the cautions I might propose and not throw cb's at all, or the cautions you have described which are clearly significant and important, I think having agreement on the message of taking cautions is a nice result.
I appreciate the discussion and learning how you approached the issue with your son.
