and kids whose parents don’t care are also messed up
The important part is balance. My kids run a busy schedule as it is. House cleaning, sports activity, school, and whatever else. Playing video games all night or the risk of them going on a killing rampage with knives/guns owned by the family is pretty low. Because they are in an environment where they can have it demonstrated that look, life involves really getting these responsibilities handled first, and some idle fun later.
Plus, TV and computers are all in the living room, fair game for everyone in the house to see, so it’s not like extreme content is acceptable.
