As far as I know, the order is: Islam / black plague / the mongols / world commu

As far as I know, the order is:

Islam / black plague / the mongols / world communism / the chinese empire’s colonization and rule / western colonialism of the americas / democracy (democratic secular socialist humanism) in all its forms / christianity in its forms.

The problem with these deaths is that both the mongols (black death), and western colonialism (a host of diseases), caused vast deaths, and were heinous, but (a) the diseases were worse than the warriors, (b) colonialism was progressive, the mongols regressive, and islam regressive and destructive, and communism regressive and destructive.

So comparing violence, diseases, institutions, and capital, and we end up with a full accounting.

A population can recover from War. It can recover from Plague. It can recover from the Mongols. But it cannot recover from islam.

why?

numbers, dysgenia, impulsivity, ignorance, impossible-institutions, low-trust.
