Being opinionate and judgmental

I have come across some very opinionate and judgmental persons.  They tend to stress me up.  I used to be very opinionate and judgmental too.  However as I age, I found that things always have many sides, it depends on which side we view things from.  There is often no strict right or wrong to a lot of things.  Therefore there is no point  for one to argue or defend his/her opinion and view point too passionately.  All it takes is a more forgiving heart to tolerate differences.
