judgemental

why are people so judgmental?
i think it's unfair to judge others based on we see.
people tend to see things on the surface.. they don't even bother to understand everything, and yet they are so quick to judge.
seriously what others do ain't our business, as long as they dont harm anyone, i dont see anything wrong.
everyone has different values and thinking. you can't make everyone be like u.. you ain't perfect anyway.
and you have to understand that humans make mistakes.. u r a human too. if u don't want anyone to judge u, don't judge others.
