How is this persecuting/harassing/driving out the 'real cowboys' in a significant way? Granted, as long as you have different groupings, people in one group will occasionally cast a critical eye at some in another ('real divers' vs. 'vacation divers,' GUE/DIR vs. 'strokes' - and in tourism, tourists vs. 'travelers'), but if someone wants to be a strongly independent fit, capable diver with excellent skills and watermanship, diving adverse conditions, spear-fishing, tech. diving or whatever tests him/herself a bit, what's stopping that person?.
