First, I don't agree that "dictatorships are stable forms of government" has seeped into our consciousness.

It's very prevalent with many people I've been talking to.

In general, it seems like you are taking one famous quote and giving in an astonishing degree of influence over political discourse while not actually considering a) how people really think about government or b) the context in which the quote was produced.

I'm using one quote to illustrate a belief that seems somewhat prevalent. I think Orwell is the most influential of the dictatorship-eternal dystopia works, but there've been a lot of others.
