you are sunni right?
ok first of all, shias hate you, shias think you are deviated from islam. they think you hate the Ahle Bayt RA and love the "oppressors" of Ahle Bayt RA (the first 3 caliphs RA). But they will do taqqiyah and tell you that you're muslim and call for this fake Islamic unity BS. But deep inside they think you are worse than kaffirs.
unfortunately for the shia, it is them who have strayed from Islam. The founder of their sect, ibn Saba, preached the divinity of Imam Ali RA. you see today the shias committing shirk by making their "imamate" (may Allah protect them from slander) higher than the Prophets AS and Angles AS and partners with Allah.
believe me, I've had shia "friends" my whole life and even was shia.
Two misguided groups are the Nasibis (i.e. Nawaasib) and the Shia (i.e. Rawaafidh). The Nasibis will take all the Hadith of praise in regards to Abu Bakr, Umar, and Uthman, but then they will never mention those Hadith which praise Ali. The Shia, on the other hand, will take all the Hadith in regards to Ali’s praises, but they will ignore all of the Hadith in regards to Abu Bakr, Umar, and Uthman’s great attributes. Both positions are biased and incorrect. The Prophet praised many people and each of the four Rightly Guided Caliphs is on an elevated status of his own.
