Salam Dear brother,
I can understand this feeling. As I have been researching this for sometime too. What I have come to understand is that different people have different interpertations and no one can tell who is telling a complete truth whether intentionally or unintentionally. So how to judge then? Just as The Guide itself tells! Let Allah and His book be the judge. All the answers lie within the Book itself and that is the miracle of this great Message. Any interpertation that creates a minutest of contradiction in any area is not right and needs to be researched on. So start from all that you are hundred percent sure about and build your faith on the truth. InshahAllah everything will fall in place. For me the start was from this reality that what we have been told by this so called no. 2 prevailing Islam is not the truth! And the only way I can reach the truth is through Allah's message Itself.
