Language is only one small part of culture. Thinking that we would not be able to transfer tehzeeb and tameez to our kids if I cant help them learn my mother toungue is almost implying that my goonga and behra kid (if I had one) would be a badtameez and badtehzeeb kid for ever. I can very well teach my kids all the manners and etiquette of our culture without forcing them to speak Urdu like Molvi Abdul Haq
