Fear of something is at the root of hate for others, and hate within will eventually destroy the hater.
George Washington Carver, American scientist, botanist, educator, and inventor, righteous Dude.
Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.
Yoda, most renowned and powerful Jedi Grand Master, known for his legendary wisdom, mastery of the Force and skills in lightsaber combat, little righteous Dude.
There is a definitive, proven, documented mind-body connection. Hate is a negative emotion, it will mess you up mentally and physically, it produces nothing of benefit, it will destroy you.
And have absolutely no effect on the lives of those you aim your hatred at, you suffer, they don't, does that seem like a good idea to you?
Put like that, it's pretty pointless really isn't it?
