The GP post seemed to start with some interesting information but then instead of adding enough substance to become a good comment, it petered out—and then it went straight to flamebait. It's correct to downvote flamebait.
Contrary opinions are welcome but need to come with substantive information. Contrarian comments that just go "nyah nyah nyah" at the majority end up having the same effects as outright trolling. It's tempting to do that, because it's frustrating to be surrounded by opponents (which is what holding a minority view on the internet feels like). It's part of maturing as a commenter to resist the urge to lash out in such situations—which is in your interests not to do, since it only discredits the minority truth even further.
