Fear itself

If the only thing we have to fear is fear itself, what about the other emotions?
Is the only thing for us to hate is hate itself?
What about love? Is the only thing we have to love is love itself?
What is the point of an emotion is the only thing you use it for is to use it on itself?
I mean, this kind of thing makes sense when you’re talking about magnets. I love watching magnets flip each other. Or drag them around through glass tables.
But fear, hate, and love?
I’ll hate fear, and love it.
