I will assume that your question is whether your fetish is right or wrong. First of all, your personal fetishes are really your own business. No one really has a right to judge what you do in private unless you are harming or violating someone else.
But, you should be aware that consistently indulging a desire to humiliate or degrade others will inevitably bleed over into your permanent perceptions of men. If you EVER want to have a normal relationship with a man, indulging your hate and resentment for them will not help you with that goal.
Think about it this way. If you had a series of bad or even violent experiences with another race or ethnic group, do you really think it would help you to go out and look for a way to engage in violence with a random person from that race? If anything, you would probably become a racist if you did that right?
So then the way for you to really get to a feeling of empowerment is do things that will reaffirm a positive image of you. A fetish is not going to help you feel better about what has happened to you. It may sound corny, but if I were you, I would take a self-defense class or martial arts. Knowing how to actually defend yourself is going to automatically increase your self-confidence.
There's all kinds of thing's that you can do besides self-defense, but just keep in mind that true self-confidence comes from being well grounded within yourself, not by humiliating or demeaning others.
