How much energy does HATE throw up (BARF) and how long does it linger in the atmosphere? Do people ever forget hate or do they nurture it?

Do they go out of their way to "remember" hate and empower it and sustain it? How does love ever have a chance to gain a toehold with haters? The strongest emotion passed down from generation to generation? HATRED of "the other"?

That is the very best of the best of the best of homo saps? Nurturing hate and vilifying love? Good job. Everyone says so.
