One of the more curious aspects of the religion of Critical Social Justice is the way in which it encourages its followers to deny the progress that our commitment to liberal values has achieved. That racism still exists is taken as evidence of the failure of the liberal project, but of course nobody has made the case that it has been eradicated. If a disease is cured but a few symptoms linger, one does not claim that the treatment was ineffective. Social liberalism is an ongoing process because it recognises the imperfectability of human nature.
