I'd argue that: 1) what is extreme changes over time, 2) a system of government being extreme de facto means it will have less support; the more support it has, the less extreme it is by definition, 3) the less support a system of government hass, the more force will be required to maintain it.
I am also under a system of government that is oppressive and monopolizes violence, but if the government had less popular support, I fully believe it would proportionally ramp up the oppression and violence. In fact, I'd argue that it's currently happening in the US.
I don't know that I agree with your definition of extreme. On the one hand, there's popularity of various ideas, and on the other, there's how much the idea differs from the way things are currently done. It's possible for an idea drastically different from the status quo to be popular, but it would still be considered extreme because of how big of a change it would be.
