I think you're deliberately being obtuse. It's not that seeing white people disappoints me, it's the fact that in the picture it's ONLY white people. I would like to see ALL American's get together and send a message to the President that we need to take care of ourselves first, we can't have the entire 3rd world on our doorstep and be expected to take care of them.
Seeing a bunch of Americans protesting for America, in what is conceivably the strongest liberal stronghold, should fill your heart with joy regardless of the color of their skin.
