Are Jehovah Witnesses harming their children with their ideas?

A Jehovah Witness lady is trying to convert my mom and I overheard her 5 year old daughter tell my little brother that she wasn't allowed to watch Scooby Doo because she is a Jehovah Witness. My mom takes my siblins to her house for playtime and it worries me that she will try to shove her crazy ideas down their throats. I consider religion child abuse towards children and don't like children to be labled as this or that. This cult almost destroyed my child hood but I survived because my mom layed off this for a while.Now I fear for my brother and sister.
