First, I don't really consider what exists in "the west" as actual democracies. They are oligarchies or autocracies disguised as democracies instead. They've always been that, only now it's becoming more obvious.

> the dictatorship is then better

No, not at all. But it does have a clear path toward something better. This doesn't make it better, but it is a silver lining.

> Why couldn't then a democracy have a revolution as well

It could, but more frequently what happens are coups - and they descent into authoritarianism. Or the authoritarians get elected.

> And how's all this black and white thinking, like because democracy is not perfect, dictatorship becomes suddenly acceptable???

I definitely didn't say or think that.
