That is a limited materialistic view, but if you recognize the universal spirit of life that unites all humans, this becomes clear. You look beyond differences and accept those who hate you because it does not have to affect you. It is a deficiency of maturity and intelligence in them. It is not about you. It is an egoic assumption of the fearful, controlling mind of conscious humans. One that you do not have to subscribe to.

If you wish to experience the freedom that comes with acceptance, that is. I am not saying love for all is the unconditionality. I am saying that when you do love someone, truly, it is without expectations and restrictions of your mind's image of what "should be."

And I meant this more in the context of familial/romantic/friend relationships.
