One of the oldest errors in human reasoning is the assumption that just because someone has immoral opponents, they themselves are moral.
If a low-down dirty scoundrel talks bad about someone, that doesn’t mean that the target of their ire is a paragon of virtue. Grifters have grifter rivals, too. And they often try to pull themselves up by putting others down, creating a roiling stew of malfeasance.
So if someone you don’t like dislikes someone else? Don’t assume they’re virtuous.
