I honestly am not a believer in the theory that movies, games, toy guns etc have any sort of detrimental effect on kid's.

If you are raised with values and morals then you know what is right and what is wrong, what is real and what is make believe. In saying that, I am not insinuating that if you are not brought up in that way that you will be a nutcase,  just that You decide what You will do later in life.

If one day someone decides to do something violent, I think it is inside them from the beginning, some kind of internal thing that no one else can be blamed for.

It is hard to put into words what I am trying to convey, but as an example - people that go on a shooting spree in a public place - they can not be normal, seriously, and I don't think playing with a toy gun or a barbie doll when you are 4 years old is going to determine the actions of that child later in life..
