Imagine a World Without Hate

I would imagine that also be a world without fear, or god-like understanding of everything essentially

Why? Fear can have logical reasons. Or illogical reasons that have nothing to do with prejudice, or with people at all (e.g., fear of heights).
Even in the case of fear of people, it can be reasonable. For example, you can be afraid that someone you didn't give a tax break to will find you and beat you up, but you should not assume only Italians would do that.
