IMO In public school, I believe they have a say but not the final say in determining what’s appropriate to be taught their children. That is, as long as the parents make the determination to keep their children in public school.
IMO Parents, as all humans, always have a right to their opinion about what the school system teaches.
I believe the right to peaceful protest is guaranteed in the US Constitution.

Homeschooling is quite common now a days.
