There is an exception to the ahistorical justification of the status quo. Some conservatives are historical realists who recognize the brutality and injustice determining the world, but are resigned to this way of the world and believe the right thing to do is ensure security for you and yours against the rest.
They could be correct, but that does not make them right. They are intellectually honest, but cowardly. To lead a life worth living and leave a world worth living in, we must have the courage to posit a better way: the possibility of equality, abundance, and cooperation.
