When hate settles into the heart, every mild action by the hated is magnified, exaggerated and made a caricature of reality. It might have been a reality in the past, but that caricature of the situation is brought into the present with every action. That exaggeration of offense grows and when it does, it becomes deadly. Why so deadly? Because it becomes easy to justify harm that is either verbal, physical or otherwise.
Be very careful of hate. It’s a lot more subtle than you think.
