Great, so you're agreeing with my point, the divine guides cannot misguide, so it's the fault of the followers for all those contradictions.
You see, the followers transmitted two images of these Imams: A- Divine leaders claiming infallibility B- Scholars often contradicting themselves and their fathers.
These two images conflict, the same people transmitting the claim of infallibility are also transmitting countless contradictions by those same Imams. These are not isolated cases, this is a phenomenon.
So now, you accuse the followers of not having preserved the teachings, of not transmitting the divine Qur'anic interpretations and of having been confused, misguided and lost in darkness (which resulted in today's mess).
At the same time, you wish for us to trust the narrations of infallibility transmitted by those same misguided and lost creatures but as for the rest we got to figure it out based on inspiration and God-given success?
Firstly, if this is the case of those inaccurate, misguided liars who attributed all the contradictions, I'd personally rather not trust their attribution of infallibility or divinity to those leaders in the first place. Secondly, "Fiqh" is not something you can guess based on some inspiration or enlightenment, you needed the Rijal system but you don't have it. If for example you have two conflicting narrations about the excrement of chicken and its ruling, you're not going to guess on your own as it is a very sensitive Fiqhi topic that can go either way.
All in all, you're simply saying the followers and transmitters of teachings, were unreliable, had no insight, couldn't determine authenticity, were misguided and irresponsible. Yet we need to trust them in matters of infallibility, Imamah and so forth? I'd rather not.
