Arguman's fallacy system is really an anti-feature. It's impossible to separate the claim that a specific argument is a fallacy from a counter-argument. Many people seem to think that you can just take a word describing a kind of a argument, attach "fallacy" to it, and you have refuted it.
Agreed. While logical fallacies are useful to teach people to avoid critical thinking pitfalls they are not useful to sift through the merits of arguments.
But is that a problem with the tool, or the lack of sufficient contribution on the topic from sufficiently interested and invested people like subject matter experts?
