Do you find people often want proof?
I think proof for such claims is a good thing. It keeps us from following leaders who take advantage of people. Unfortunately, Sufis for example, have leaders who claim position of inheriting the Messenger and having right to establish rituals on his behalf.
Many of these leaders even most Sufis would acknowledge are crooks that take advantage of people, but then don't see in their own leaders. They will see other leaders taking people money and controlling but won't acknowledge it their own.
The way Sufis present that there are many crook leaders but we can find a good leader who is what he claims, is unrealistic. We end up just choosing who want to follow or the first person we meet or whatever reasons, but not based on the truth.
And this especially since nothing distinguishes on leader from another.
I don't think we can choose leaders and who to follow. Even Quran shows Mohammad (s) was contended and ridiculed and people would say why not God reveal the reminder to a great man from the two cities.
I don't think we can recognize leaders if they don't have proof. I would not pick Ali (a) for example, if it was not the designation from in the Quran and Sunnah.
Once we follow the leaders from God who have proof of their pure status, that we make their teachings, a standard by which we elect government. But government and authority in that regard should not be a game and people are to really put the fallible leaders to high standards and make sure they don't deviate from it.
Simon (a) was selected by God and Jesus (a) but he is not infallible, and if he did mistakes, should be corrected, and if he deviated, abandoned. The church saw itself as infallible because it was appointed to represent God and Jesus (a) for a period of time. The same has occurred with Shiite scholars. Although divided, people don't see it's possible we have deviated much like the Church eventually deviated.
And the heart of that deviation was when scholars put themselves at a higher purity status than others. That they are to be seen as more pious and more reputable in religion.
Unfortunately, I find myself between a rock and a hard place. I can't abandon the scholars and their politics, lest, we throw away religion and it's role as a guide in all spheres of life. Yet, knowing they have deviated from major teachings, my non-revolt is like what Imam Ali (a) described about his patience with Abu Baker's caliphate... "So I adopted patience, although there was a mote rankling in my eye and a bone sticking in my throat on seeing my heritage [the caliphate] being plundered"
I will find the right means inshallah, at the right time, with the proper etiquette.
