Expecting children to use false pronouns is imapcting upon them, and their rights, their instincts and their integrity. it is also presenting children with a harmful untruth.....and suggesting to them that they must go along with it.
The parents of the child with 'pronouns' are making a special case of their own child.......expecting everyone, and all of the other children, to indulge them. This is unacceptable and is a terrible thing to teach or expect of children when in a vulnerable situation away from their parents.
If this is what the camp organisers are expecting then they will surely also be implementing intimate mixed sex situations within the camp, and without the parental consent of the other children.
