That may be easy for you to say. Especially with hindsight. One family gathering your uncle has convinced you Hillary Clinton personally killed those men in Benghazi and the other your mother-in-law is afraid Trump is going door-to-door groping women. People find their echo chambers, it's especially easy to find the one you're currently leaning towards with Reddit. Human beings and the synthesis of their thought processes is more nuanced than a choice between liver and onions and feces. All that matters is that they recognize their mistake and they won't make it again. Your comment helps nothing, in fact you'll realize the only purpose it serves is to raise the insignificant pedestal on which you've decided was enough to display your ego.
