The globalists know that they have to indoctrinate the youth in order to get them on board with their agenda. For people on the right who are not on board with the globalist agenda, it makes sense that they do not want this type of indoctrination in schools.
There are multiple mentions of the importance of getting the youth on board with the agenda in the "Pact for the future" by the UN.
"Action 20. We will accelerate the implementation of our commitments on youth, peace and security. 41. We recognize that the full, effective, safe and meaningful participation of youth is critical to maintain and promote international peace and security. We decide to: (a) Take concrete voluntary measures to increase the inclusive representation of youth in decision-making at all levels in prevention and the resolution of conflict, including by increasing opportunities for them to participate in relevant intergovernmental deliberations at the United Nations; (b) Strengthen and implement existing youth, peace and security national and regional road maps to deliver on our commitments, and develop them where they do not exist, on a voluntary basis; (c) Request the Secretary-General to carry out the second independent progress study on youth’s positive contribution to peace processes and conflict resolution by the end of the eightieth session."
Today’s generation of children and young people is the largest in history, with most of them living in developing countries. They are critical agents of positive change and we welcome the important contributions of young people to peace and security, sustainable development and human rights.
