Violent games are causing violence and giving kids bad ideas. How do we know that? Because violent games that are explicitly racist, or turned against rich people, or gays, or Jews, don't really exist (or if they exist, they get banned). Why would such games be banned, if they don't cause copycat behavior?
If you believe those fake "scientific studies" they've "proven" that violent games actually reduce violence, because kids do virtual violence instead of practicing it on street. Well... following that logic, they should allow games where you only shoot black people. Because then racists will practice virtual racism, instead of real racism. Right? Nope. Because we know such games could condition youngsters to think that racism is okay. Which is why those games are banned.
Which proves the fact, that games cause copycat behavior. Even though game vendors won't admit it and they are ready to finance "independent studies" to prove that games have absolutely no influence on the brains of kids. Which is total BS. Everything you watch or hear influences your brain.
