Re: I have accepted Shiaism…
That is exactly what shias say. If you had even a vague idea of shia beliefs then you would know that shia’s consider Hazrat Ali to be infallible and hence superior to all other ashabs including your other three khalifas, therefore “doosro ko nasheeat” saying doesn’t apply here as it just happens that the most suitable person for the khilafat happen to be a relative.
This is exactly what shias believe that the basis of khilafat should be character and how can people be judge of chracter, therefore khilafat of rasool, (like the khilafat of previous prophets as stated in quran) should be decided not by ijmaa, or shoora or saqifa, but rather by God and since God (through Rasool Allah) appointed Hazrat Ali as the rightfull caliph, the fact that he happend to be family of Rasool is irrelevant.
There are ahadiths among sunnis that khilafat could only be among quraish (slogan of some ashabs right after rasool Allah’s wafat) is in direct conflict with the teachings of Islam.
Here is what was said in saqifa from sunni books.
“Umar said: When I saw that they wanted to cut us from our root and wrest authority from us, I wanted to make a speech, which I had composed in my mind. As I used to treat Abu Bakr with gentle courtesy to some extent and considered him more sober and gentler than me I conferred with him about the speech. When I wanted to speak he said gently so I did not like to disobey him…He said 'Now then: O men of the Ansar, you deserve all the fine qualities that you have mentioned about yourselves, but the Quraysh, for they represent the best in lineage and standing. I am pleased to offer you one of these two men; render your oath of allegiance to any one of them you like. Thus saying he took hold of my hand and that of Abu Ubaydah b. al-Jarrah”.

Poonawalla, the translator of this edition of al-Tabari then adds a further segment of the speech of Hadhrath Abu Bakr to the Ansar, under footnote 1343:
"Baladhuri, Ansab 1, 582, cites the speech of Abu Bakr which shows how he argued against the Ansar. He states: “We are the first people to accept Islam. We are in the Center among the Muslims with respect to our position, and we are the noblest with respect to our lineage, and we are the nearest to the Messenger of God in relationship. You are our brethren in Islam and our partners in religion…The Arabs will not submit themselves except to this clan of Quraysh…You had not better compete with your Muhajirun brethren for what God has decreed for them”.

In extolling the virtues of the Muhajireen, Hadhrath Abu Bakr also said that they were:
“the first on earth to worship Allah and were the patrons and the clan of the Prophet who tolerated and suffered with him and adversities and injuries inflicted upon them by their own folk who disbelieved them and all other people opposed them and alienated them”.

Halabi further expands on Hadhrath Abu Bakrs’ words:
“We are the relatives of the Apostle…and therefore we are the people who are entitled to the caliphate…It will be advisable to have the leadership among us and for you to be the Viziers”.

Now do you see which sect beleives in importance of lineage and which one beleives in importance of character??
