People who get involved in a particular sport are picky about terminology and the tools of the trade. Don't mistake a revolver for an automatic with gun people. Don't call a sheet a line with boat people; and God help you if you call either a rope. But in my experience, bicycle people are the worst.
See, with bikes if you aren't training for the Tour de France, forget it; you're nothing. If I go walking, dressed any way I like, I wave to other walkers and they wave back. If I go shooting I talk with the other shooters about their equipment and it doesn't matter to them if I'm dressed properly or have the "right" gun. But with bikers, sheesh! If you don't have the right kind of bike and wear the de rigeur rainbow, spandex clothing, many of them will not give you the time of day when you pass.
Good thing I like guns.
