The problem, if you want to crystallize the worldview, is secular humanism. SH teaches that people are basically good and there is no need for any oversight, no family, no parental authority, only blue sky and the goodness of the person to keep society in order. SH affirms that all people are special and capable of determining their own gender/preferences/logic/future, etc. Moral absolutes are replaced with situational ethics. Absolute and universal ethics are replaced by cultural norms that are pliable within historical eras. People aren't special because they're valued by their creator, they're simply bags of matter and cells that can be expended at will. Please consider the schools themselves and their informal teaching from 5-18 years of age, to be the issue at hand. Not simply games that appeal to males.
“There is no God and no soul. Hence, there are no needs for props of traditional religion. With dogma and creed excluded, then immutable truth is also dead and buried. There is no room for fixed, natural law or permanent absolutes …. Teaching children to read is a great perversion and a high literacy rate breeds destructive individualism … the child does not go to school to develop individual talents but rather are prepared as “units” in an organic society …. The change in the moral school atmosphere … are not mere accidents, they are the necessities of the larger social evolution.” ~John Dewey (signer of the Humanist Manifesto)
“In the New Order, Socialism will triumph by first capturing the culture via infiltration of schools, universities, churches and the media by transforming the consciousness of society … “ ~Antonio Gramsci (1891-1937)
“Education is thus a most powerful ally of humanism, and every American public school is a school of humanism. What can the theistic Sunday schools, meeting for an hour once a week, teaching only a fraction of the children, do to stem the tide of a five-day program of humanistic teaching?” ~C.F. Potter: (1930)
