And as someone commented on a previous thread here, their presence with trolling arguments causes the thread to become 'contentious' so the HN algorithm knocks it off the front page. I've no doubt that for some of the trolls that is the objective. It's a pity because this is probably the most important issue of our time and it's going to take an engineering/scientific approach to solve it - so I think it's highly relevant to HN. There are some sharp minds on here. It should be hotly debated and the ranking algorithm should be able to take the heat.
