Do I object to rapid fire?
Genuine rapid fire doesn't bother me. That is, aimed, accurate, rapid fire. What does bother me is the shooter who takes up the position immediately to my left and begins the brass shower.
Or the near-full auto fire that goes down range splintering target frames or richocheting over the berm.
So long as you are safe, non-destructive and don't encroach on someone else's pleasure, then I have no contention with rapid fire. But when rapid fire starts detracting from the pleasure of other shooters, then its time to show a little consideration.
Good manners apply at the range, too.
