Parents should decide what their children are taught; their influence should be primary. They are the ones raising the children. They are the ones paying for their children's education. If teachers and schools are going to continue to take parents' money, they absolutely cannot shut parents out of making decisions about the materials being taught, especially sexually explicit ones. That should be and remain their right. Any content that isn't reviewed by parents should never be presented to children.
Our children do not belong to the government, and it is our job to keep them safe! Keep education in the hands of parents!
