You have been taught to hate, either by your own negative experiences, or by negative experiences/perceptions of others, or by agenda-driven propaganda. 

Yes, true. You can also indoctrinate yourself (self-indoctrination) by leaving your critical faculties unused.

But, don’t worry!

A learned behavior can be changed. Just remain humble; tell yourself repeatedly that you are teachable. 

There’s no shame in unlearning falsehood and embracing universal truths.”
