"In Brighton, for example, the local council tells schools that if children are questioning their gender, their parents don’t need to be informed. This guidance even states that school staff may want to use a child’s preferred name and pronouns at school, and birth-registered name and sex-based pronouns in front of parents. Parental deception, in other words, is not just accepted but encouraged."
It is beyond me why schools think teachers are qualified and competent to flat out lie to parents like this, and then expect something that is in 'public' within the school buildings to never leak out through other kids and parents in the outside world. You can't force a whole community to keep a secret and then expect the poor parents to pick up the pieces.
