I really hate that my wife is a feminist.
What's wrong with her being a feminist?
I'm a misogynist, all women should focus on men's needs
Your wife should be able to support whatever cause she deems fit. If that cause is feminism, that's perfectly fine.  You may also want to reexamine your own views about women.
She should be ashamed of herself
She shouldn't feel any shame about being a feminist. Feminism holds a lot of great values towards women. I'd recommend looking into what feminism is all about and I think it would really change your view on it.
