Conservative: I am happy with the Status Quo
Reactionary: This government has failed to defend the Status Quo
Liberal: I want political reform
Anarcho-Liberal: This government will not give us political reform
Socialist: I want social reform
Communist: This government will not give us social reform
Fascist: I am angry about something but find it difficult to articulate exactly what it is.
Well done, but you are essentially using only one criteria across your spectrum: reform vs. status quo. This gets you close, but raises several contradictions as Safferli pointed out in his initial responses.
A very useful ideological spectrum can be found at the Political Compass website, where the spectrum is a grid defined by:
- Libertarian versus Authoritarian
- Collectivist versus Individualist
This is nearly as simplistic and abstract a design as what you have proposed, and yet allows for a much more accurate rendition. Notice, for example, how this system does a much better job of explaining Fascism:
