Well, discrimination is the quality or power of finely distinguishing. It is recognition, perception, or identification especially of differences. It is the act, practice, or an instance of discriminating categorically rather than individually. Prejudiced or prejudicial outlook, action, or treatment. It also means damage. Detriment to one's rights or claims.
It can be healed in many ways. For me it is by making them friends. Love your enemy. Never discriminate each other. You should be friends with them. If you want a story about it, look in the Bible for Luke 10. May God bless you.
