I dont know where the idea that there are no bad opinions came from, it doesnt actually make sense. An opinion that doesnt use logical reasoning, and is actually illogical, or ignores evidence is what I would consider a bad opinion. So I'm telling you that you have an opinion that seems at this point impossible to back up logically. The idea that because some extraordinarily low percentage of children commit murders underneath the age of 10, their parents are justified in betraying their child's trust and looking through their journal (and in this context then posting that information online) is illogical. Whether or not you pick and choose where you decide to learn valuable lessons doesn't matter to me. I'm just pointing out that knowing when you've lost an argument is a valuable life skill.
