Koran is too small to make a religion. Koran does not contain enough information to explain itself even. This is why, muslims have to depend on books other than the koran. It really sucks for people like you, who are looking to save their dignity from the claptrap that exist in their culture/religion. But I am very sorry, the koran is not enough to make a religion.
How do you know how to fast, how do you know how to pray, how do you know how to perform the hajj? how do you know the definition of zina, or fahisha, or noshooz? On which case do you apply whipping? What is nikah? is nikah marriage? how come? How do you even know how to do the 'Arkan - Corners of Islam' when the koran does not give enough information?
You can keep protesting against the hadith all you want, muslims have an answer for you, 'Science of Hadith', and unfortunately, very unfortunately that is, the stoning in the hadith, does not contradict the whipping of the koran.
Cheers and sorry if in this situation, reality, did not conform to your goal/wish in life.
Ruling has to come from Quran not from hadith. When quran say lashes, that's the final verdict.
Any hadith after that means nothing.
