The thread is about how to eliminate hate, I think. For this reason I wonder here about the reasons for hate. In any ways shooting whoever you hate is effective in eliminating hate, because you forget him after. What would you do to eliminate hate?
Hate is reactionary. Hate is usually brought on by a threat; a threat to ones livelihood, a threat to ones family, a threat to ones security or safety, but a threat.
You didn't wake up and say "Boy, I really hate that Barak Obama. He was okay yesterday, but I really hate him today!"
In order for you to hate somebody, they had to present you with a reason first--a threat.
If we can be realistic here, does anybody murder another person without hating them?
