I have been taught by my gods that fear is the flip side of love and that hate stems from fear.
I may be splitting hairs but as type, I do not believe I am. One can vanquish their fear and thus extinguish their hate. People can rationalize their hate for any number of perceived personal affronts metastasizing into resentment, but once they realize whence it arises, then they can eliminate the source of hate so that Source can re-enter their lives.
