What is the objective way of measuring "greatness?"
What does public opinion have to do with it? Does majority rule--here expressed, I suppose, by things like television viewership and endorsement deals--always trump expertise, intimate knowledge, and educated observations?
Is applying a wider historical context somehow less "objective" than not doing so?
Finally, why can't people of good will have differing opinions about the relative "greatness" of different bicycle races without name calling, accusations of trolling, and other expressions of heightened emotion?
