After reading about early Islam, it seems evident to me that the Shiite version of history is the objectively correct one. There is pretty much no denying that Ali was the chosen successor and the Quraysh just suppressed it. It's rather astonishing that Sunni Islam is as dominant as it is and Sunnis defend the early caliphs so much given how obvious it is that Umar prevented Muhammad from writing his will and most likely assaulted his daughter leading to her death.
