Hegemony is very distinct from the white supremacist movement. While white supremacists probably promote hegemonic practices, this does not mean that some engineer who didn't take the time to think about people in circumstances very different from his/her own is a white supremacist. Sadly, dominant members of a hegemonic culture (read: pretty much every culture) participate subconsciously to reinforce the hegemony simply by not being aware of it.
I understand that you don't like the Real Name requirement, but pulling out the Big Gun Labels like this is akin to calling Larry Page the New Hitler. It's not accurate, and all you're going to do is make people angry.
Oddly enough, a lot of who used to be "white suprematists" are these days are more of the non-hegemonic cultural-separatist types, heavily influenced by postmodernism and postcolonial theory in the "right of Peoples to self-determination" sort of sense (at least those associated with the 'New Right' theorists). You end up with strange spectacles like French nationalists getting along well with right-wing Turkish nationalists, Japanese nationalists, or Israeli nationalists--- they all agree that they'd like to observe each other peacefully from a distance, in each group's pure, mono-ethnic country, each with their Glorious Histories and whatnot, maybe with the occasional bit of tourism, but definitely no immigration.
So is your argument that the system does not promote cultural hegemony, or that it is not intended to promote cultural hegemony? Because the latter, while it may be true, is largely irrelevant. I think it's entirely possible that you can get forces that promote hegemony as an unintended consequence of seemingly innocuous design decisions, or else as an emergent phenomenon of complex systems.
I'm not trying to call Larry Page the new Hitler, rather I'm just pointing out that there is an existing word for what Danah Boyd and others are describing.
ender7 (an ironic name) did not refute the idea that the system promotes hegemony. His issue appears to be with your conflation of hegemony and white supremacy.
Your argument is a classic logical fallacy- "white supremacists want hegemony. We have a hegemony. Ergo, the system is run by white supremacists"
