Moral Highlander
Someone who thinks that when you're complaining about or trying to fix a problem, it means that you don't also care about other, possibly bigger problems because "there can only be one" thing that you care about.
Every time I say we need to bring back net neutrality, Carl moral highlanders me with "Well, I guess police brutality, kids in cages, and our crumbling health care system are all fixed, then."
