If you put a gun to your head and pull the trigger, that is stupid. Anyone who says "Uh, that is stupid" is not being "judgmental", they are stating the obvious.
Do you walk into fast food restaurants and go from table to table calling people stupid? Or do you only have courage to search out threads on internet discussion boards?
I think the operative scripture would be "Why are you concerned with the mote in thy neighbor's eye and ignore the beam in thine own?"
