Note: The opposite of love is apathy, not hate.
False.
You've limited yourself to a concept that's not relevant to this discussion; though I'm sure well intended. Sure yeah, love is the opposite of apathy in regards to caring vs. not caring; so what? What does that have to do with this thread? Look at the context of what you're saying vs. what the OP said. Now look at all of the facts...
Fact: love *is* the opposite of hate, but then Love has many opposites doesn't it? Why?...
Class, let's open our dictionaries to 'love'; notice love is a verb, love is a noun, and there are several definitions. For clarification, the OP is talking about love as a noun (intense emotion or "powerful" force; as in, "the force of love"), not love as a verb (caring for someone). Are you following the simple logic?
For grins, let's compare love to its opposites:
LOVE AS A VERB: love (caring for someone) vs. apathy ( )
LOVE AS A NOUN:
love (intense positive emotion) vs.
hate (intense negative emotion)...or the object or force that possesses the emotion; such as, "God is love; therefore, love is the most powerful force in the universe."
Just throwing this out there...
Notice in books like the Bible, there are references to love and hate in the same sentence (as opposite ends of the spectrum).
I hope that helps put things in their proper perspective.
