Viewing the world in absolute terms IS one of the main causes of hate, in my opinion. The idea that a group of people can be convinced to view something as absolute makes them malleable to do things they wouldn't otherwise do.
For instance, you are absolutely against hate. Now all someone has to do is change your definition of hate. Even in a subtle way. Now you are absolutely against something else you may not have been before. And this absolute disgust for something can morph and become something completely different than it was before. And you will never question it because you have absolutely made up your mind and there is no other way.
The world is not black and white, in any way. There are only shades of gray. There is no such thing as absolute good, and there is no such thing as absolute bad. Please examine this in yourself before you become a tool for someone else's agenda.
