There is nothing wrong with the media. The violent people cause the media to be violent. the social media is a great way to stay in touch with your friends, but when a violent person gets on the social media like: instagram, facebook, or twitter and they are violent on there, that makes it violent
you arrangement is irrelevant for the fact that on all these social media sites allow you to block out people that are being violent to them or just not accepted there friend request cause why would you want to be friends with someone that is going to start something with you and media violence is more about what kids watch on TV and what they play as in games more then some social sites
you sound like your 5 years old. On telivision and movies they have ratings were they give restrictions for the violent in them, such as PG, PG-13, and R. and on telivison before every violent show they saw "veiwer discresion is advised".
