Granted, if you don't love/like yourself that much, the subject statement takes an entirely different tone.
However, I'll interpret it in the context it was given. I've been involved in some discussions in various places in the manner of love and how it's expressed/handled/so on. For the most part, it was on the 'agape' love. In the Christian sense, demonstrated through the Good Samaritan parable, Jesus' sayings and his sacrifice. And as a way of living in general, regardless of religious beliefs (or lack thereof), 'do unto others as you would have them to unto you' is one of the best ways of living, as it forces one to put him/herself into the shoes of another and evaluate consequences of all actions.However, in terms of the 'agape' love, I was coming across a sentiment of one loves his/her neighbor because that is how one expresses love for God, or because Jesus said to do that, or because it's how we show we've changed. But I never saw the sentiment of I love my neighbor that violently disagrees with me and everything I stand for. As in, not just loving the neighbor through acting in a loving fashion, but literally loving without a an iota of hate or scorn. All you hold towards the opposing side is pure love.
Now, I'm sure there are a lot of people who do hold that sentiment of loving through actions and an internal mindset -- but it wasn't common in the discussions I was having. So my thing is ... is it really love if it's only in the action? Because I can act in a loving fashion to all sorts of people, while remaining apathetic about them emotionally, or even hating them. In which case, I'm loving on the outside, but not so much on the inside. Which would make me a hypocrite, because if I don't love that person in an internal way, then do I really love the person at all? I can say and show that I love the person as much as I want, but I'd be lying.*
If still holding this in a Christian sense, the crucifixion was the culmination of the 'agape' love. And that love wasn't just confined to the action. Jesus wasn't crucified while filled with hate. He internally loved them during the whole process. I'm not dismissing the actions themselves, because oftentimes it's the only way we can love someone, and it can make a great starting point. But, in the end, it looks like there has to be something deeper: a willingness on one's part love through-and-through.
So I would say that when God calls us to love a neighbor as ourself, we have to do much more than just act loving. We have to be willing to forsake everything else that might justify a negative feeling we'd harbor towards another.
As always, much easier said that done.
*This would be using the term 'hypocrite' in a rather unusual sense, because it's not along the lines of saying one thing and doing another. It's more of saying one thing and feeling another.
