Let them be humbled by their mistakes. Let them be reminded of their mistakes so they learn not to do them again. They will earn their repentance by being silent and being forgotten by the public. If they speak up again, we will remind them.
Indeed. If folks are finally starting to wake up to things, they shouldn't be harassed for daring to admit they were wrong.
HOWEVER, that's not a blanket pardon to allow those people back into your lives.
Judgement will be reserved until we've heard what they have to say. Dismissing them entirely because of past follies is little better than ignoring them outright because we don't like their politics.
