agree, but under the current circumsatnces how much you try to avoid in indulging in such discussions, one or next incident happening in the society lead you to that discussion. I myself try not to indulge in such discussions, I would rather try to deviate discussion towards weather, some TV program, but its not always easy. Say you have a dharna either by Jamat e Islami or Majlis e Wahdat ul Muslimeen on some killings. People will start with traffic jams and then end with Rasool allah ka deen Vs yazeed ka deen.
