Hate has absolutely nothing to do with fear. That is totally illogical and inept thinking. One need not fear to hate as one need not hate to fear. The to are totally disconnected.
It may be that people have different concepts of the two. Let me ask you to name something you hate and then list root causes.
I hate insane jealousy. Because it brings the worst out of some people.
I do not hate envy because some can be sanely envious, and learn from those who they envy and become better people themselves.
Jealous nations have needlessly destroyed Jewish nations and other good nations.
Jealous Jews have destroyed themselves...
Therefore, I hate jealousy.
