It bothers me how many people are morally incurious, and it bothers me even more how many people seem to think that interrogating morality is proof of immorality- because I'm pretty sure that the latter is at least partly driving the former. Asking why an action or institution is wrong does not necessarily mean that someone thinks that that action or institution is right. If you never ask yourself why something is wrong or right, then what is determining your morality? Because it's not you.
