We are all brothers in Christ, Sons of God called to return to Him. We are meant to live in Gods home, his kingdom. But like brothers, when we live away from our Fathers home, we must live apart from another and love each other. A brother who stays in his brothers home is bad, for it makes them resentful and competitive. You must love them and pray for them, rejoice when they do Good as much as you would for when yours do, and mourn when they fail as much as you would when yours fail. If they are truthful, they would do this too wholeheartedly. But remember, that as God gives first to the Jew THEN the Gentile, so too must you give first to your Kin THEN the Others. You should expect the same from them.
We are also sojourners; like the Hebrews in the Desert. We are charged to carry cloaks and swords. We must be willing to use them.
Tl;dr dont hate them, but understand where to draw the line. If you find yourself hating them, learn to forgive and love and ask forgiveness yourself. But never let that be an excuse to be weak.
