You seem to have nailed the issue therationa! You've actually stumbled onto the very reason Jesus wound up being tortured to death - the fact that his entire purpose rotated around love. The thing is that Jesus was very specific about what love actually is, whereas you've adopted the bland Disney version which is nothing but a caricature of Jesus' idea. According to the Bible, "God is Love" - not "God is loving",  a description of him that we can interpret based on our own philosophy of what love is. The idea is that love is not a concept but a person - our actions only qualify as love if they resemble his.

In short, Jesus' teaching on love amounts to "hate absorbed is hate defeated". He was not advocating standing there waiting for bad men to hit you, he was talking about storming the enemies' territory to bring care for the broken, understanding for the hate-filled and forgiveness for the hopelessly messed up. That sort of thing makes people want to hurt you; that's why he wants his people to turn the other cheek.

You look at His teaching in the same way as the people did that heard him - impractical idealism. Why should they love the occupying force of the Roman army when they should be fighting them and achieving political freedom? Because Jesus was not interested in a political kingdom but in "the Kingdom of Heaven" - the character of God that "speaks up for those who cannot speak for themselves". People that don't value their own lives or possessions as much as they value the welfare of even their worst enemies. You're right  - it's not a way to get rich, but Jesus suggested that there were even more important things than money and personal health. Important enough that you would be prepared to lose everything standing up for God's big three priorities justice, mercy & faithfulness.

It's not popular - Israel has always rejected it. You see them still with more of an interest in political freedom than in love; how well is that working out for them? I'm not singling them out  - Jesus' teaching is no more popular with "Christians" either. As he said "the road is narrow and few travel on it."

If you want to know what Jesus' love looks like, look at what he did, look at people that tried to live it out like the Reverend Dr. Martin Luther King. Ghandi thought it was the answer to the world's problems even though he was a Hindu. If you're interested, I have some thoughts on it at http://bloodwoodtree.org/war/.
