This post is going to be extremely unlike me. I'm going to quote the New Testament, and I'm going to say that it's an insightful passage that everyone could learn from:

"You have heard that it was said, 'Love your neighbour and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your brothers, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect." -- Matthew 5:43-48

That's an insightful passage that everyone could learn from. Strip out the weird "tax collectors" and anti-pagan parts, and you have the core of Jesus' message: Unconditional love. What's so damn hard about that?
