I don't hate anyone in this world. There are many people I have little or no respect for. But hate? No.
The way I have learned to deal with anyone who seems to cause problems for me: I just cut them completely out of my life in all aspects, and move on. I break off contact... step one. Rid myself of any connections I may have with them... step two. And part with the sentimental items I've kept in the past which I still associate with them... step three. Then, I forget them and move on to brighter and better things. I don't ever give them the satisfaction of holding my attention, good or bad.
