Because a movement whose sole principle is to change language to remove the possibility of offence to minorities and disadvantaged groups does not seek to influence how people organise themselves, or how government is run, or how funds are allocated, or on what basis a state conducts itself. It may have a secondary influence on political discussion, and perhaps a tertiary effect on actual policy, but that hardly counts as a political theory, because we expect a political theory to say something about politics. It's more like a quasi-ethicised theory of semiotics.Bozo Erectus said:Why isnt it a political philosophy? If ones concern is primarily focused on not being offensive to former victims of colonialism, how can it possibly be independent of politics?
What you were proposing for PCness is that it is a way of looking at the world that fundamentally colours many people's view of the duties of government, of the appropriate means of economic distribution, of cultural practices, and of international state action.
