Knee-jerk hate might be a beneficial strategy if you're trying to survive in Darfur, but we safe people should try to minimize it for the benefit of our own minds. We learn and grow by studying things, especially the things that rub us the wrong way. The other benefits of arbitrary hate like feeling you belong to an in-group seem out of place on HN, a site mostly devoted to curiosity (from what I've seen).
I'm not saying you should or shouldn't feel or act a certain way, but for all of our sakes lets keep it mental and not bring that sort of thing into the public light here where it might be perceived as community endorsement of that point of view.
