Violence in video games

i have to present a speech and i was wondering why people think that video games are the primary source of demoralization and hate crimes.
if you do not think that video games make people violent, can you please give me a few reasons why you believe they are not violent.?

why do they blame games? cos those "in charge" are retarded. the end.

it's a blame game. have to blame something. cant possibly be tv or even politicians "leading" by example can it?

humans are inherently violent. goes hand in hand with ignorance. blaming something other than your own culture is easier than facing reality.
