Stupid stupid parents.
Here is a study that should scare the heck out of them. TV has been shown to cause autism.

Sorry, but in that study, they didn’t even study children who watched tv versus those that didn’t. They looked at the autism rates in 2 states - California and Pennslyvania I believe - and compared that to cable subscription rates and precipitation rates in those states.
To me, that just does not demonstrate a causal relationship. There could be any other number of variables coming into play.
