Forgive me for butting in, but sister Hirah sound's as though she has very little knowledge on the subject matter. I think she should focus on the basics before she can fully understand the information being bombarded at her. The problem at times is people expect a simple answer to what is a rather complex question, "The differences between Sunni and Shia". It is greatly upsetting that Sunnis do not know the extent of the Shia deviancy. The Shia have the audacity to slander the wives of the Prophet, the Mothers of the believers and yet we laugh and joke with them. I dare anyone to do the same if they had sworn at your mother.
