Don't get me wrong, I love CrossFit. I live it, breathe it, and love coaching it.
But CrossFitters can be ARROGANT. We believe in our program, after seeing the results, and absolutely believe its the best way to train. Not exactly "CrossFit" per say, but rather high intensity training, constantly varying up the exercises and making sure they are all functional real-world movements.
CrossFitters often make mockery of bodybuilding movements, such as cable curls or whatnot. The thing is - a CrossFitter seeks fitness. He or she looks back at the time they did cable curls, and laughs about it, because they realized thats not fitness. In truth they are right, but that's not the purpose of cable curls. No, cable curls won't bring you to new heights in fitness, so it is silly. But it is a widely used exercise in bodybuilding, and it as proven it's worth. Sort of a miscommunication to a certain extent between CrossFitters and bodybuilders.
Far too often, we as CrossFitters say this program is THE ONLY way to go, and ITS THE BEST, SECOND TO NONE for fitness purposes. This arrogance naturally creates resistance against the program, and its something I too need to work on. I'm very proud of the program, but I respect all forms of exercise. The only bad exercise is no exercise!
Also... hogging 15 different stations at a globo gym and making a scene can also be annoying to other members as well. More of a reason to join a CrossFit gym, where that type of training is meant to be done.
