It’s funny you say this since there is a fallacy fallacy, in which one assumes that the conclusion of the argument given must be false because the argument uses a fallacy. I think this usually comes from a place where people are looking for a gotcha moment rather than sincerely engaging with the topic, and I think the big pitfall of the fallacy fallacy is that it feels like you’re engaging honestly and sincerely. So yeah, it’s better to engage with people honestly rather than assigning malicious intent upon detection of a logical fallacy.
