It's difficult indeed to develop the mental strength necessary to oppose a system of oppressive values that has already been internalized. The oppressive morality -- for morality is a set of principles governing behavior -- has become part of you. That is why your arguments seems to defeat themselves. This is also why Bataille says, you need to change your consciousness and simply start thinking differently about the world, if you want to be free. Don't succumb to the tyranny of forms: that which cannot be defined is totally free.
