How do you deal with entitled riders on crowded MTB trails who seem to think the rules dont apply to them, and what strategies would you use to diffuse a potentially volatile situation when encountering a rider who is clearly not following trail etiquette, but gets defensive when called out on it? Is it better to just let them go and avoid confrontation, or should you take a more direct approach and risk escalating the situation? Are there any specific phrases or tactics that can be used to politely but firmly remind someone of their responsibilities on the trail without coming off as aggressive or confrontational?
