"But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes."~ 1 John 2:11 (ESV)
It's a powerful word. It's more than simply not caring for the target. It's disliking with a passion, a venom. Personally, I've never hated and been happy at the same time. Joyous feelings have always been pushed out by feelings of anger, bitterness, and sadness.
I'm a political junkie, and when certain politicians come on the news, I've been known to tell the room, "I hate that *#$&%!" While I was weighed down by bitter feelings, the politician in question was oblivious to my self-inflicted emotional suffering.
As negative as hate is, it seems to be everywhere these days. People belonging to racial minorities hate the police. Pockets of white America hate people belonging to racial minorities. Hard nosed Christians hate gays & lesbians. Our political leaders hate each other so much they won't sign bills sponsored by the opposing political party.
Hate is pointless.
Hate requires time and energy. The time and energy we dedicate to hate is time and energy we're not spending on something fun and/or productive, and the hater is the one who loses out the most. Lets axe it from our schedules and our lives.
