Right or wrong

Why does someone always have to be right or wrong?  It seems to me that this is the basis for every argument and every disagreement today.  As a society and beyond we are naturally and unnaturally always trying to find the answer to something.  To prove something true or to prove that something is false.  Why?  Often times it seems to be at the cost of someone else’s beliefs, integrity, morals etc.  I feel that one should believe in whatever they want to as long as it is not directing causing harm or danger to someone else.  What about simply respecting an individual as they are?  Quite frankly I’m tired of the constant debate.  You’re wrong and I’m right.  I don’t feel that any one person is wrong for the religion they choose, the things they believe in, their sexual preference etc. just because it differs from mine.  “To disagree or to agree, it will never actually matter or determine anything for certain”..jlr
