People need proper education for living in this world properly and no body knows what is proper way of living in this world properly.
Almost all people everywhere think they can sort out problem by senselessly fighting with each other.
All do to each others what they complain about against each other. Take any ground upon which people divide to say we are great people and others are devils.
Are religious people treating each other nicely? No. Look at what hindus, parsis, jews, christians, muslims, sikhs are doing to each other.
Take any religion in the world and see that these people are fighting with each other as sects.
Take secularism and you will see exactly the same thing happening. World is full of warriors. This is why wars are always going on between people.
People use anything and everything as an excuse to try to do something bad to others for their petty personal gains. This is the way of life we all have adopted to live by in this world. So all of us human beings are corrupt and tyrants to the core. How can we change for better? By learning proper way of life and then adopting it fully and wholeheartedly. Does anyone want to work on that? Only a tiny minority. So things will carry on as they are till we do what needs to be done. For better understanding of deen of islam from the quran see
HERE,
HERE,
HERE and
HERE.
Till people have the policy that they are not going to let each other live in peace, peace will always remain a distant dream no matter who comes and who goes. To have peace between them people need to unite instead of dividing. How can they unite? By studying the quran properly and teaching it to each other properly, not the mullaan way. The quran teaches proper way for managing humanity and resources so that all things are delivered to all points of need freely and on time.
God has given us already whatever we need and it is totally free for building a great world for ourselves ie things to use and and guidance about how to organise and regulate ourselves to make proper use of them.
Look at surah annaas ie 114. What is this surah about? Not for making imaginary jinn things runaway. It is about seeking refuge or protection in God. How do you seek refuge in God? By adopting his advised way of life for living in this world. When people will learn and live by that way of life they will no longer be a danger to each other. Instead they will do all they can for each other for sake of God. Imagine the kind of human society that will come about if people came to know the real message of the quran.
