The State shouldn't being doing the parent's job.
It's like these breakfast programs at school. Are you kidding me? If a parent can't pour their kid a bowl of cereal in the morning, the Children's Aid Society should be investigating.
And when the parents aren't doing the job?
You realize CAS is "the state", right?
But prior to that, it's teachers, friends or other parents who may notice problems with a kid, especially if they go to school.
Here's a question, what if the child's parents are abusive because the kid is/might be gay/trans? And abusive goes anywhere from physical to emotional abuse.
