Can our individual FAITH in GOD be a source of Conflict?

[Mey]

The history of mankind has been a history of conflict: conflict between two brothers (cain vs abel), between black and white, between nations etc...until now there is conflict everywhere..Do you think it is possible to have a world without conflict...Are the people of the world capable of living together without conflict among themselves? Do you think our individual faith has something to do with this conflict? WHAT DO YOU THINK?

Yeah we can unfortunately confess this bitter fact that the zealotry and nationalism or favoritism exists from the history and still it is going on, however a better human is one who doesnt care for the languages, religion, skin, height, beauty difference and treat everyone human equitably.
