I believed in the power of love

I believed so strongly in the power of love. I believed a loving person could achieve anything. And so they can... unless someone with greater hate is motivated to throw obstacles faster than the lover can surmount them. In my life planning, I truly underestimated the strength of the power of hate. Is this the classic left wing weakness? Believing that hate is weak, and then finding out too late, when battered and bruised, surveying so much destroyed and broken, that even in its profound spinelessness, hate is actually very strong indeed?
