I have become a little aggravated by people who don't believe in dark matter

  why? Until direct evidence and predictions of properties emerge, from an epistemological point of view it's still a very shaky model. If it all turned out to be epicycles it wouldn't be surprising. Or maybe a better analogy is Vulcan. https://en.wikipedia.org/wiki/Vulcan_(hypothetical_planet) https://en.wikipedia.org/wiki/Vulcan_(hypothetical_planet) The closest we have come to direct evidence are the independent calculations of the properties if it's a self-annhilating particle that agree with a certain set of observations. Even so that seriously breaks a conservation rule, because if there's no proposed way to create dark matter, the universe makes no sense.
