As an American I can say that when the Religious Right had power here in the late 20th century they wielded it like a sledgehammer just like the SocJus tards on the Left do now and were just as happy to cancel people they didn't like.I think OP you're a little optimistic about the old guard such as the religious right being able to forgive; anyone who lived in Ireland during the Free-State era up until the fall of the Catholic Church in the early 90's can tell you that the authorities were anything but forgiving for perceived "sins". Institutions such as the Magdalene Laundries where girls were sent for sins including being too pretty, being sighted near boys and having a single mother for a parent went on to serve their entire lives in unpaid slave labor because they were "fallen women" beyond forgiveness and redemption. This wasn't a late Irish Catholic novelty, but historically something that existed across the globe in states where the Catholic faith was ascendant.
That's merely my favourite example, but a cursory look at European history shows that forgiveness is only a virtue to a group while it isn't the dominant force. The Early Church was relatively pacifistic until it gained power, as were the Protestants until they gained the upper hand over previous authorities. It goes for secular states and organizations as well, the French middle classes suddenly realized in the late 18th century they could harness the lower classes like a sledgehammer to crush their social betters.
I don't agree with everything Nietzche said, but his description of slave morality comes to mind here. Forgiveness is a virtue for the oppressed, and not the oppressor. We are now in an age where both the Radical far right and left command authority over states or significant enough numbers of people forgiveness, a form of compromise, no longer needs to be considered within their echo chambers. It will resurge when one side falls and becomes set upon by the victor and they suddenly realise it's actually beneficial to them once again.
