Cold meat- did you read any of the op.
Toy guns- I meant your basic Walmart plastic toy cap gun which you can point at someone's eye and not hurt them. These, it could be argued, give children in their formative years the impression guns will not hurt you.
Video games, by there interactive nature, unlike guns, provide an educational process for learning violent behavior. The do this by punishing non-violent behavior...character dies...and rewarding violence...long play time and points. Humans can be taught effectively using this logic...Do you have CBT training at work?
