I think you have missed the point of duality. So I ask, What is the opposite of love then?
I will give you the benefit of the doubt, and perhaps you simply have a different understanding of it.

To do or not do, to be or not to be etc. ... and all the principles of which we speak have their opposite, (which makes them whole) and integrating the opposites is one of the lessons of the physical plane...
