Compassion is not a popular virtue. Very often when I talk to religious people and mention how important it is that compassion is the key that it's the sine-qua-non of religion people look kind of balked and stubborn sometimes as much to say what's the point of having religion if you can't disapprove of other people?
No matter what message you are about to deliver somewhere whether it is holding out a hand of friendship or making clear that you disapprove of something is the fact that the person sitting across the table is a human being so the goal is to always establish common ground.
I disapprove of what you say but I will defend to the death your right to say it.
