> The comment is pure ad hominem You got that wrong. Listing the many ways in which someone doesn't know what they are talking about is a statement of fact, not a personal attack. If I argued a bunch of nonsense on HN about an article on biology and someone called me for not having a clue, that would not be a personal attack, they would be factually accurate. Biology is not my thing. Sometimes we just need the truth.
