Or the commenter was simply a troll. You get them on almost every news site now. Commenting on every article with something that will most likely cause others to argue / start a flamewar. I'm not sure if that needed a response at all. People not used to internet commenters sometimes give in too easily and start feeding the trolls... it only wastes your time and gives someone more chance to have "fun".
Trolls and griefers are a real problem, there is not so much that you could construct that can not be destroyed by a small number of motivated people, online as well as in real life.
Creation takes time, energy, intellect and inspiration, destruction can be done instantly, requires much less energy, zero intellect and pigheadedness will do just fine.
This is the most obvious answer. Taking it too seriously and upvoting articles like this will only ensure /b/tards find out about it and initiate an even bigger trolling.
