Thank you Margaret Rose ;)
What I meant is that hating someone is a personal decision, but the reasons that fuel hate are mostly social.
Someone — a group, leader or influencer — feeds division by portraying a particular segment as ‘evil.’ They encourage their followers to hate those than don’t belong to their same group or don’t think like they them.
Note: I used ‘anger’ as a synonym but they are not necessarily the same. I don’t know if that caused some confusion.
Anger is an emotional reaction triggered by something done by others that frustrates us. Hatred lasts longer and is more pervasive; it’s overwhelming and blinds us. Hate makes us want to attack or hurt the other.
