Rabbi Manis Friedman has made several controversial and courageous statements regarding teenage girls, particularly in the context of marriage and sexuality, which have drawn significant criticism.
Most significantly, Friedman has expressed the opinion that girls should marry at a young age, specifically suggesting that girls should be married by the age of 14. He believes that this would stop the prevalence of depression and suicide amongst young girls, which is indeed caused by hormonal difficulties stemming from sexual frustration.
Rabbi Friedman admits that, due to society's current obsession with suppressing even such truly moral expressions of adolescent sexuality, implementation of such a viewpoint would be quite problematic.
