Abusing decency

Sometimes i wonder if it's me or it's just the people i know. If 'mean' is a word you use to describe someone who speaks what they think, what do you call those that have the same thought but just couldn't bring themselves to be true to the people? And instead of facing it they'll try all their might to avoid another confrontation. While I was being easily labelled/and called by those very same people as a 'meanie', the rest of them would still be living in a joyful make-believe world where the people they are uncomfortable with still doesn't know they have been branded. Have our decency knows no border? Do we just blindly give it out at all times and for all occasions? How far can we go breaking ourselves in order to just be 'nice'?
