Your Reply: You're right. But they're not.
At least we agree on the principle that there should be full and open public scrutiny. While I agree with you that there in many cases the schools will try to do things in the dark, away from public observation, this is completely inappropriate. Now, we can discuss the way things are endlessly. It is better discuss the way they should be, and to try to get to that point. At least we agree that schools should be completely open to observation.
Parents and taxpayers hold the power over the schools. They should assert their rights and perogatives aggressively, or else the schools will not respond. Any person who complains about the schools and has not run for school board should have some explaining to do.
It's just not practical.
If her daughter had attended against her express wishes. If she had not been given the opportunity to keep her daughter out. If her daughter had been forced to attend. If there were any consquences whatsoever to her daughter not attending.
If...
Then I would agree that Ms. Loveless has a valid beef. She doesn't. She knew what the material was. She kept her daughter away from it. End of story.
