the mask of civility is the thin veneer that liberals use to hide their agenda
it’s related to the difference between materialist and idealist perspectives
if you claim to uphold lofty ideals, then you can just claim the material failure to live up to those ideals is an oversight, mistake, accident, victim-blame etc
this is also why plausible deniability is a critical aspect of many operations, it was those few bad people that caused the bad things, not the institutional structure that is dedicated to lofty ideals
