Study: Online system for reserving national park campgrounds has equity problem

1) The idea that non-white people can't figure out how to use a website well enough to reserve a park reservation is far more racist than any concept I've ever seen out of the most vile communities. How is this not roundly mocked and condemned as science?

2) Rather than inequality, is it not possible that different groups of people simply have different interests? Maybe certain population groups are more into camping than others? Shouldn't this be considered as a diversity of approaches to life and not necessarily racism?
