Racism happens to all races on the river including caucasions. I am caucasion and have experienced racism when I was fishing around another race (will not discuss which race as it does no good) as well as for being a redhead (ps us gingers will take a lot until you push too far, then run, the temper is a true redhead trait lol). It happens to a lot of people, I've found it depends on the friendliness of the people you are fishing around, not the race or what they fish with. Some anglers have this believe that they are better than others because of the way they fish, and some believe they own the river. When I approach I always ask for permission, its just commen courtesy but seldom see it used by others (goes a long way with some people). Best thing you can do is be respectful of others, friendly and know your regs, fish etc before you go to the river and always pick up after yourself (including not throwing your cig butts down the river, filters do not break down easily and fish will eat them from time to time). A lot of people get pissed off if you ask about regs or type of fish as it is your responsibility to know before you go to a river, not someone else's responsibility. Personally I know the regs but still carry a set on me in case my memory fails me. There is no excuse for racist comments but if you are yelled at for misidentifying a fish or not knowing your regs, it is your own fault for being yelled at (not the racist comments though). If you feel threatened either leave or call the cops, its not worth your time or effort to fight a racist as it is unlikely you will change their point of view and may in fact make the person more racist if it becomes heated instead of a logical calm conversation. There are enough places to fish that if you have an issue find another spot. In this day and age you never know what a person will do or what they are carrying on them, as I had a guy I was fishing around that I was talking to and joking with about beaks with only to find out he had a handgun on him to "deal with such people" , and that is why I am a firm believer in being respectful and courteous when approaching other anglers.
