I'm proud of my country, I'm proud of my race, and I don't hate minorities for theirs.
So much technology was invented by white people. I don't hate non-whites and I don't take personal accomplishment of what other white people did, but if Americans can be proud of their country being the first one to land on the moon while those Americans never went to the moon (while not claiming Congolese are inferior for never going to the moon) and not be called racist, then I feel I am entitled to the same liberty.

In this context, white power!
