A Thought for today

A question keeps returning to my thoughts of late. In part I think it arose because of all the turmoil around us: in the United States, in Europe, the middle east and indeed, almost everywhere . My question needs an answer: Do we need to have enemies? Do we need to dislike or even hate, those who think differently or those who look differently or those who are, in some way, not like us? Must there always be and 'us' and a 'them'? Is it not possible to be able to say: I don't agree with you but let's get to know one another and explore all the other riches there are in each? How boring our world would be if we all looked, or thought, or spoke or worshiped the same way.
