1) Its a waste of electricity
2) There is a lot of religious programming that your kids will inadvertently be exposed to. Do you really want to expose them to that? Many shows have religious episodes (Christmas, Easter etc). Do you want them to be indoctrinated? (does this break your rule?)
3) TV doesn’t inspire creativity in children. Is creates kids who are lumps, don’t use their brains and don’t get excersize because they are sitting there entertained without doing anything.
4) TV is likely to harm your vision if you watch too much.
5) Often, people leave the TV on too loud and can cause partial deafness.
This is fun – I love arguing the other side.
