If you dont care about race, why even bring it up? The only people I have ever scene bring up how they dont care about their race, heritage, culture, blah blah blah are typically the ones that care a great deal more.
When I read a WF post I never consider the race of the poster (unless blatantly pointed out). You are simply identified by your avatar, and username. If I met you in real life you would be that mixed guy that I hang out with, and I would be the white guy you hang out with. Its just the way of the world.
