HN is definitely not an echo chamber; we see here quite a variety of positions on many controversial issues, and the great thing about HN is that we often see really good and well supported arguments on multiple sides of an issue, because if you can't support your argument with some verifiable evidence, you'll get downvoted very fast. HN does, however, have its own version of the Overton Window[0], meaning that some positions are outside of what is acceptable to argue and those get shut down fast as well. This is the case both on technical issues where it is probably driven by the range of acceptable opinions among the Silicon Valley elites, and on social issues where it overlaps quite a bit with the mainstream media's Overton window, but maybe has a somewhat more libertarian spin (again, because that's common among the Silicon Valley elites).
