I don't have to repudiate my faith to reject the Da'esh.  They don't represent a majority among my Sunni brethren, and they don't represent we Shi'a at all.  That's why they want to kill us.  Doesn't require me to be delusional to conclude the Da'esh ain't Muslim.  All it requires is an understanding of the fundamentals of the faith--which you clearly do not have and therefore aren't qualified to 'inform' me about my faith--as well as a modicum of common sense and self-preservation.  Da'esh want to kill all Shi'a Muslims.  I and my family are Shi'a Muslim.  It's therefore not a logical stretch for me to hate them.  It is, however, a logical stretch on your part to 'lump' me with them.  But then, bigotry is seldom logical.
