Most "bike" lanes in my area are Multi-Use Paths (MUP). This places a cyclist in traffic with pedestrians, many using headphones, dog walkers, strollers, joggers, skateboarders, etc. I find this a hindrance to cycling for a workout, let alone a hindrance to those cyclists in training. Fortunately, though those shouting get off the road do so a bit louder where there is a separate trail, there is no apparent sentiment for denying a cyclist use of the road ways.
