What on Earth? Is being nice now a qualification for damnation?
You cannot change a heart with hatred, I am sorry, plenty of people have tried that approach, picketing and saying that God hates gay people (as though they are qualified to speak for God) or sending them to Gay conversion therapy and it does not work! The only way to change someones heart and mind is with the Love of Christ. If anyone comes to Love God, they will Love to do what pleases Him. Anyone who does not Love is nothing, and that is Scripture!
