The Shia do not argue for anything, our faith is between us and our creator, we do not need to impose our beliefs unto others as in Islam there is no compulsion. Sunnites just have a hard time swallowing the fact that there others who disagree with them, so they resort to lies and hypocrisy. They hate Shia for things their very own Sahabah did, like slandering Lady Ayesha, mutah, sahabah doing shirk by worshipping the Prophets hair, and cursing sahabah. Sahabah did all that plus killing other Sahabah, yet its the Shia who are hated. They qoute the weakest hadiths of Shia and try to pass them off as authentic, yet they get angry when the same is dont to them, they generalize and twist many things on Shia, yet hate it when the same is done to them.
They claim to love all wives of the Prophet but they built toilets over the house of Khadija AS, they claim to love the Imams, but slander them by calling them gods, they claim to love Ahlul Bayt but theu praise and love all their killers and abusers like Mauwiyah and Yazid.
