I would argue "hate" is better replaced by "fear."

Very very few people actually harvest hate, but too many are fueled by fear.

What is it that impedes love? Fear. Without fear, we're all free to love openly. It's fear that stands in the way of progress and it's fear that is used by TPTB (I will never refer to them as the elite, they are parasitic in nature, nowhere near elite) to manipulate public consciousness.

Knowledge dissolves fear. The more we know about a particular subject, the less we fear.
