Great post @shimmerz, really gets your brain going. For me, I think that the opposite of love lies within each situation, and can vary based off of the topics presented. If we are talking about people, and/or living things I think the opposite of love is fear. I love people who are brunettes and redheads, but I'm totally afraid of blondes. I love dogs, but I'm afraid of what bugs do to me (side note: I'm severely allergic to misquitoes). If we are talking about inanament objects or things that are hard to conceptualize as living, than the opposite of love is indifference. I don't care what happens to a lamp because there's no personal connection to it. Therefore I can treat it however terribly I want without feeling guilt. You could also conclude that if you dehumanize a person or group of people, you will feel indifferent towards them and not feel guilt when you treat them badly.
