If a teen girl really wants to have sex, get pregnant, become a teen mother and risk her education and future economic security, there's nothing I can do to stop her.Fortunately you are not allowed to force your cookie cutter mold of bourgeois narcissism and contempt for society on teen girls. Teen girls are free to reject your fear mongering and misandry, and become a loving wife and mother, living a virtuous and meaningful life, while making a worthwhile contribution to the future of society.
Fortunately, teen girls are free to reject YOUR backward ideology, and pursue all their educational and career goals, which has a much greater chance for giving them economic independence. That's far better for a teen girl than being totally dependent on a man for money her entire life.
Education + Job Training = Career / Economic Independence
