When people have an emotional reaction to something you say, do not allow yourself to lose your cool if you know that you meant what you said. Do not be apologetic either, when you are saying something you mean, if you know that what you are saying is for the betterment of those people you are saying it to. If someone is hurt by what you say and you feel their reaction is over-the-top, stand your ground and explain yourself as opposed to being apologetic. Everyone has emotional triggers and it is not our job in this world to appease people's emotions, but to speak the Truth. If the Truth is too much for someone, they need to look at themselves in the mirror as opposed to blaming you for making them feel bad.
