If we're talking about the Internet, then whites likely are a minority. Not that I'm making some passive-aggressive appeal about this, just highlighting the absurdity of clinging to your racism on a network that defaults to being oblivious to details of the wetware we're running on.

Or for that matter clinging to the idea of counting discrete persons as opposed to eg Sybil. Or do we count by routable IP addresses, so carrier grade NAT is the modern three fifths compromise for the developing world?

Or are you really implying that by controlling speech on the Internet, we can eliminate racism in traditional localized society? Because if you actually care about reducing idiotic bigotry, and I think you do, then I guarantee you that's really a great way to create more of it due to resentment. A corollary to "the Internet interprets censorship as damage and routes around it" is that by the time you've achieved a victory for censorship, any chance for mutual understanding has long been squelched.
