Dear my friend, first of all welcome to our Steem-bounty family, we are very happy that people like you join this friendly place and start to have many conversation as Steemit should be.
Regarding your question, this is a matter of university teacher, because religion is too big thing to be discussed in few words.
Anyway in my opinion, religion should teach love and respect of each other, but it is unbelivable how this is the reason where we have so many war in the past and you can see the actual situation where everybody is worry about the difficult of integration withdifferent religions in the same countries.
Of course there are political reason too, but i remember before 11/9/2001 nobody was worry to travel around the world and now we are full of fears.
I am not religion praticant, but i believe there is a God which will give the mean of this life to everybody.
