The oppression the victim pretends to suffer doesn't exist, and so he is permanently looking for evidence of his oppression. He even helps searching for evidence. The oppressor and the victim are each other's necessary complement. In his turn the victim needs the oppressor, because the oppressor is the only one who will acknowledge him as a victim. The liberals play different roles at the same time.
Many liberals play both roles.
Here we see two souls living in the same chest. The man who is predetermined to play the role of oppressor, but refuses to play his part, is banned from the intellectual community. He is called 'reactionary' or 'fascist'. One could think he's a threat to the system, but that is not the case. On the contrary, the oppressor needs the reactionary as badly as he needs the victim.
