Racists violate the principle of equality by giving greater weight to the interests of members of their own race when there is a clash between their interests and the interests of those of another race. Sexists violate the principle of equality by favoring the interests of their own sex. Similarly, speciesists allow the interests of their own species to override the greater interests of members of other species. The pattern is identical in each case.

The hope of internet anarchists was that repressive governments would have only two options: accept the internet with its limitless possibilities of spreading information, or restrict internet access to the ruling elite and turn your back on the 21st century, as North Korea has done.
