general douchbaggery?... Like holding a grudge on a coach that hasn't coached your team for 3 years?  
Or blasting some guy that disagrees with paying big $$ for custom lures or paint jobs? 
Or classifying all the fishing jersey wearers as goobers? 
I've had old men pull in and throw across my line, had wrapped boats pull in on top of my fishing spot, but I've encountered MANY more people that were just as respectful as most of us try to be. 
Table Rock is a big lake, if some one encroaches on me I usually just go somewhere else. It's not worth getting mad about, especially since I had a friend get shot a few years back near Hot Springs. He's lucky to be alive, all over a fishing spot. 
I just think it's stupid to place a "tag" on someone just because they wear a particular shirt.
