Funny - You yourself are admitting that "you will find more important stuff to read other than killing the Non Muslims" .
You are admitting that your Quran states killing of Non-muslims. So, U live in India U say. Is there any other religion than your Quran that says kill people who don't follow that Particular Religion.
Regarding India - the Parsis knew that hindus are tolerant of other religions and that is why when Islam spread by sword in Persia, most of them decided to take refuge in India. Hindus gave them land and they have lived today peacefully following their religion without Fear.
Regarding why everyone is not understanding your true Quran as you say - is because you have already given the answer " there are more things in Quran other than killing the Non Muslims". Look at Kashmir where the Muslims are in a majority and they have driven away the minority Hindus to live as refugees in Hindu Majority India. Did U ever ask yourself why your Muslims brother have done it. So, don't pose questions to others rather to yourself.
