Our language may or may not be underdeveloped.Your states of UP/Bihar and your sick mentality are on display here.The pains for propagating womens' education were taken by Mahatma Phule and Maharshi Karve and that has seen the modern educated Indian women express herself confidently and helped India's progress.In UP, the father-in-law rapes his own d-in-law,an apt reminder of the quality of your culture that prefers to keep women under wraps and claim themselves and their culture/language to be better/supeior to that of others
