Many historical apologies for slavery and illiberal government were based on explicit or implicit voluntary contracts to alienate any natural rights to freedom and self-determination.
Those who hold this view sometimes point to the existence of illiberal democracy and liberal autocracy as evidence that constitutional liberalism and democratic government are not necessarily interconnected.
Somehow illiberal governments never seem to learn that harsh measures against those who fight for freedom and democracy stiffen resolve rather than weaken it.
