I'm bringing up Ford and Gandhi because I think they're generally considered respectable, but could be accused of being in the category of those to "shun" based on verbal statements or opinions. I am not aware that either did anything. Are we shunning people because they've advocated opinions that in their time weren't controversial, but are now?
Bill Cosby's conviction was overturned on a technicality. Do we shun him even if the courts couldn't/didn't convict him?

Or similarly, "unconvicted" but alleged unsavory characters, perhaps pop musicians, TV hosts, presidents, presidential candidates, and so on.
Do you just shun everyone who has simply been accused of misconduct? What if the accusers recant or are found to be lying? It's happened.
Crystal Mangum, now incarcerated for murder, has recanted her rape accusation against the Duke la crosse players:
