This is the true challenge of Christianity: to love despite ourselves. So we are clear, this does not mean simply accepting all ideas as equal, nor rolling over on our principles, nor not defending ourselves or our beliefs. It does mean that we should work at trying to make the world a better place by both our words and our example, and that we should strive to understand even those with whom we disagree. That which we truly understand we cannot help but love (I believe this idea is in the novel Ender's Game).
