That's exactly why Sayyed Al-Khomeini ruled that Mu'awiyah was not najis.
Although other Shi'i scholars disagreed with this reading of history, but if it can be proven that Mu'awiyah did not fight out of hatred, then he was not najis according to the mabani of Al-Khoei and others.
Alhamdulilah, one more thing we all can agree on without going around in circles. My contention, however, is with the word games. Is it usool al-deen or madhhab?
One learned Shia brother stated the following, "The Usool Al-Deen and Furoo` Al-Deen is not mentioned in ANY hadeeth.
The scholars have put this together much later on. So you won't find aHaadeeth from the Ahl Al-Bayt (as) that says. The Usool Al-Deen says, 'The Usool Al-Deen is....and the Furoo` Al-Deen is....'. Actually there is a Hadeeth that talks about the pillars of faith, and it looks like the Sunnee's pillar of faith, but with Wilaayah put in there."
When asked for these narrations, he cited:
“I requested Aboo `Abd Allaah (as) ‘Teach me, please, the principles of beliefs. The Imam (as) said, ‘They are: to testify and affirm that there is no one who deserves to be worshipped except Allah, to testify and affirm that Muhammad is the Messenger of Allah and to affirm that whatever he has taught is from Allah. (It is of the principles of beliefs) to affirm and accept that there is 5 salaah (prayers), to pay Zakaah (charity), Sawm (fast) in the month of RamaDaan and to perform Hajj of the House (of Allah). (It is of the principles of beliefs) to love those who love us (‘A’immah from the family of the Messenger of Allah), to disown our enemies and to become part of the group of the truthful ones. (All such issues are of principles and obligatory matters).’”

“Aboo Ja`far (as) has said, ‘Islam is based on five principles. They are: Salaah, al-Zakaah (charity), Sawm (fasting), Hajj and al-Wilayah. The call to none of the other principles has been so emphatic as it has been to al-Wilayah. People accepted the other four but they left aside this [al-Wilayah].’”

Why would people accept the other four but leave the simplest one out? Wilayah, like belief in redemption through Christ, is just a belief. Of the five, it would be the easiest of them all (to abide by). The key phrase in all of this is, "The scholars have put this together much later on".
Brother Nader also referenced his own blog (where he has shared the same hadiths):
http://www.revivingalislam.com/2010/09/5-foundation-pillars-of-imaan-faith.html In the comments section, some brother, Wasil, commented by saying, "Wilayat is from furu al-islam and it's one of the pillars of iman and without it iman is inadequate
but to say that everybody who doesn't believe in it is kaffir is very extreme and contradicts quran and hadith."
The question I have, then, is, why believe in something so problematic which contradicts the Qur'an and Hadith? Why even bother giving it different spins or painting different pictures of it? Which one is easier? Having endless discussions which lead us no where leaving a vast majority of a population of 1.7 billion in doubt, feeling as though they may have violated Islam, or simply admitting that it is not in the Qur'an and Sunnah? And if it is not in Qur'an and Sunnah then adios, bye bye, see ya later!
