The purpose is to see whether your stand is right or not. We human has a natural instinct which is when we decide or choose anything then we tend to believe that this is 100% true/right. We forget that five fingers are not same.

100 people has more than one opinion. Something is right for you does not mean the other one is wrong. In a community if i decide what is right or wrong then I am deciding considering my interest (nobody is above their own interest not even the angels, angels are doing all this good work because they want to make their GOD happy, which is an interest). I believe when it comes to a collective of people than we should back up the higher percent's.

In this forum the reality is not (may be) what the mass says on this post however as a community we can see what the majority thinks.  Hope it make sense for the purpose.
