> A society with a pragmatic regard for its own survival would ban it outright
Western society would cease to exist if it didn't continue its diabolical lies, falsehoods and abuse. The lies are not optional.
It is because of pragmatic regard for survival of the status quo that the lies do continue. That word 'pragmatic' is what keeps diabolical people from seeing themselves for what they are.
You say that like western culture is the worst here?
Where is it better? Russia? Where stating that a war is a war can get you in prison? China, where historical events, like 1989 at tianamen square are wiped out? North Korea where everyone cheers up to the beloved genius leader?
