I get the sense that my leftist friends think it a curiosity of history that in communist countries, one in ten (the precise number varied by country) people was a government informant, condemning others to hard labor or death.
The complicity in mass slavery and mass murder should not seem distant and far away. Just imagine people like yourself: trembling with rage at the perceived injustice by members of the oppressor classes. And screaming with the mob for your rightful bounty which, tantalizingly, lies just one execution away.
(Because you couldn’t possibly be responsible for your own failures. No way. It is the fault of the oppressor class.)
