By Christian tenets, hatred of someone is a sin. It's also unproductive. Hate eats away at the person experiencing the hatred, without harming the person hated in the least. Hate is a self-destructive emotion. That's why so many people try to transform hate into scorn and ridicule. These emotions are less self-destructive. It's a self-preservation reflex to mock and laugh at someone you would otherwise hate. Both emotions are wrong for Christians, who should offer love to others where possible, and remain neutral in their emotions where it is not possible. Put the hatred on Jesus, and let him carry it, by saying "God's will, not mine, be done." If God wants to strike down the person you hate, God will do so.
