This says exactly what I feel about the link between mercy and tolerance.
Yet mercy is not a given. It is a value we must nurture and aspire to. Tolerance allows the spirit of enquiry the confidence to roam freely, to make mistakes, to self-correct, to be bold, to dare to doubt and in the process to chance upon new and more advanced ideas. Without mercy society grows inflexible, fearful, vindictive and humourless.
As far as I can see, cancel culture is mercy’s antithesis. Political correctness has grown to become the unhappiest religion in the world. Its once honourable attempt to reimagine our society in a more equitable way now embodies all the worst aspects that religion has to offer (and none of the beauty) — moral certainty and self-righteousness shorn even of the capacity for redemption. It has become quite literally, bad religion run amok.
