Have you ever remained quiet when someone said or did something awful and stewed about it afterwards? I have, many times. It actually feels a lot worse than challenging the person about their behaviour at the time it happens. Being a peace lover is not the same as being a peace maker. Making peace involves standing up for yourself and holding the other person accountable for what they have done and said. Whether they choose to take responsibility or not is not under your control, but it is your answer as to whether it is worth your while having this person in your life. Setting and respecting your boundaries creates genuine, authentic peace. It's good for you and ultimately good for the other person, even if they don't realise it at the time, or ever.
What often stops us from challenging another person on their behaviour is our fear of conflict. So we stay quiet. Which often gives implicit permission to the other person to continue with their bad behaviour. They don't seem to mind conflict, in fact they might even thrive on it. But I can guarantee if you challenge them and stand up for yourself, they'll soon get pretty tired of being rude or unkind, if only because they don't want to listen to you challenging their behaviour.
