I came to understand hate as the result of unfulfilled 'love' experiences. For example, one would come to 'hate' one's parents if your expectations of them being the most ideal parents are not fulfilled. Within this we merely jump from love to hate without any practical understanding of, in this case, where one got such ideal of 'love' from and how it is that we come to blame/hate others for not fulfilling that idea within ourselves. It's quite a mindjob to say the least and the only thing that it creates is just a rambling pole-to-pole type of logic wherein there's no self introspection as to how you even created such 'love' in the first place, what you define love to be and how you come to create 'hate' as a result of not getting your love experience. All based on experiences.
So, it's easy to continue rambling on everything one loves or hates, but without questioning WHY and HOW you have come to hate or love, then it becomes a rather useless writing too. That's how writing it all out in itself might be a first step as 'rant and rave' however from there it is about using writing as a tool to start questioning yourself and your love/hate premises does become a platform of self-assessment and introspection, so that's how we use words/writing for here.
