Every conceivable human action is potentially a moral issue. By that I mean that in principle there could be an argument as to whether it is right or wrong. It's an essential consequence of it being a human action. So you couldn't have an argument about whether having indigestion is right or wrong, but you could about whether having a bacon sandwich is, maybe with a vegetarian or a Muslim or Jew. A Mormon might argue similarly about drinking coffee. The fact that we may think that some activity is a perfectly legitimate thing to do means that we are treating doing it as a moral issue, just as much as if we had the opposite view.
