but who am I to assume I’ll be “better” or whatever than my parents?
As someone who is probably closer to your parents age than yours I can tell you that if TV, movies or books were then what they are now, your parents wouldn’t have plopped you in front of them. I grew up with a TV in almost every room, and my brothers would watch all the time. As soon as the shows got a bit less appropriate, and we were older by then, my dad started making rules about what we watched. You probably also are too young to remember (or know) that there were only a handful of channels and kids shows were only on for a certain period of the day. To say that your parents let you watch all the time as a basis for allowing kids to do so is comparing apples to kiwi.
