The way to reverse this trend is to end the political indoctrination in schools. School choice is one piece of the puzzle, as well as returning control of the schools to their local communities.
Education is certainly a major factor and one key on the cultural piano that I have been banging for years.
School choice would certainly help as would returning control of the government's socialist-entitlement K-12 schools to the local communities. One step at a time. The final goal should be complete separation of school and state.
Fundamentally, nearly every teacher in this nation was trained by godless Marxists in Marxist run colleges and universities. This is true from pre-K through university graduate school in both private and government schools.
Scary! Yet...Where is the urgency? What are conservatives doing to confront this threat? I don't see much.
