As a whitey (blonde hair, blue eyes even) I have ZERO problem with other races having tats like "brown pride" or even the slightly-racist "affirmative action" movement - which was used poorly as an example by xxpillowxxjp.
But if I ever saw someone with a white pride tattoo, I would instantly think he was a trashy racist POS and would consider hate-criming his face off. Anyone who defends it as being in-equal is racist, incredibly naive or just arguing for the sake of arguing.
I would somewhat agree with this statement. Although both Brown and White Pride tattoos could at least be theoretically considered to have the same basis the fact that White Pride tattos carry such a strong stigma attached to them that you basically your accepting that upon yourself. If you know and everyone does that society is going to view you as a racist than choosing to accept that stigma means you have to agree with the beliefs your being labeled with.
