everyone is influenced by everything they see, at least a little bit.
but you can't go through life thinking like that, or you'll just end up censoring everything, and it still won't make any difference.
There have been bad people since the dawn of time, if its not tv, there will be something else to influence them.
Best way is to educate, not censor, make people smarter so they can make better decisions... works much better than making people ignorant.... thats when they make stupid decisions.
