no body has forgotten the karbala. but who killed to whome. did sunnis killed hasan (RA). are you gone crazy or what? you are uttering something nonsense now. please talk sensful things....
islam is the islam only and any one who follows the tenets of islam will called muslims only. be it shia or sunni. in fact even if a hindu starts following and preaching what Quran says, he must be called a muslim.
there is not difference between shia and sunni. we are all muslims and one ummah.
