I know very well the Shia and Sunni rift. One just needs to familiarize oneself with Iraq to figure that out. They both share all the fundmental beliefs, holidays, submission of women, rejection of outsiders, low of Dhimmia, embracing Sharia Law and the terrorist culture in the demonic religion. The rift is a political rift. Sunnis belief the warlord to replace their original child molesting, mass-murdering war-lord prophet should be Abu Bakr (a warrior, rapist, mass-murder, xenophobic psycho like Mohammad) who was 2nd in command to Mohammad. Yet Shia think it should come from the family of Mohammad, meaning to Ali Tallib. It was a pissing match of who leads the cult on their next quest to spread the infestation by the sword!
