That is not clear at all. They might simply disagree with the methodology and that is a legit topic to discuss. More importantly if you actually think he is trolling the best route to go is to disengage and downvote. This doesn't distract from the discussion or degrade the discussion into name calling. Also hacker news rules are to respond to the most charitable interpretation of the users point. Assume they are disagreeing in good faith and engage with the topic or disengage and down vote if you feel the users contribution is negative.
