No, Doug Sanders, you are wrong.  Mass murder, including mass shootings, may be terror in its most basic sense, as in fear, but it is not always terrorism (note the headline cleverly did not say "terrorism").  Terrorism is by definition either targeted or indiscriminate violence in pursuit of a political goal or ideology.  A goal may yet to emerge in Vegas shootings, but so far we do not know.  This has nothing to do with skin colour.  Anders Breivik and Timothy McVeigh were terrorists; as far as we know, Stepehn Paddock was not.
