"Do parents have a constitutional right to prevent their children from receiving education in public schools on subjects they disapprove? Almost never. Parents do not have veto power over the content of public school instruction ... If parents choose to place their children in public school, parental rights are generally outweighed by the state's interests in educating students... The right to notice and opt-out also does not apply to discussions of gender, sexual orientation, and family life outside the context of sex education.
Nobody ever stopped me from informing my children what I thought was right, wrong or whatever.
