who says that our culture is based on Islam. Its vice verse. We got customised version of Islam incorporating our cultural garbage in it leading to problem you mentioned above. Islam is simple and easy to follow code, but we love to mirch masale , halwe maande wala Islam. We got our own Diwali in the name of Shab e Barat, Ganpati visarjan in the name of Eid Milad u Nabi and Taaziya taboot of Muharram. We love to have Bhajans in the form of Qawwalis. Our ladies got their version of Panch Kaniya in the form of Dus Bibiyon ki Kahani.
Islam is not present in its simple form in sub-continent. If it had been and implemented in true spirit, things would have been much better. Its been defaced and now been blamed for the crimes its not responsible for. This is like ‘khaya piya kuch nahin, glass toRa 12 aana’
