All I'm taking from this is that people often misapply shallow knowledge of logical fallacies. Look, not all reasoning is equally good, and the fact that no essay is a mathematical proof doesn't mean that we shouldn't point out problems in reasoning. If someone sees mysterious lights in the sky and thinks that it was aliens, that's not entirely invalid -- but because of a false dichotomy and confirmation bias, the assumed probability of the lights being aliens got exaggerated. tl;dr version: fallacious reasoning should be guarded against not because it automatically destroys any argument containing it, but because it skews our estimates of probability.
