We do need to teach people to be more caring in general, and that insulting people is not a good thing. We also need to teach people to not take insults so personally. To look at it and think "what is so bad about that? Do the bad points apply to how I'm acting?" There is no either or with teaching. Teach both! We teach people both to not steal and to lock their doors, don't we? We teach not to do it, and the defenses against having it done to us.
Being bossy is not the same as being a leader. (see pics below) Bossy men are not congratulated. They are called assholes, or dicks. Nobody likes to work under them. Nobody likes to work with them. Some people like having them as their assistants, but nobody likes it when a bossy person has authority over them.
