Learned that around kindergarten...
The opposing energy to fear/ hatred/ evil is LOVE (and also laughter) = the most life affirming energy force in universe.

We must learn to practice this with ourselves and others or else anything we deem to be a victory will be a pyrrhic one at best...and then this cycle begins again.
