I have no issue with CF itself because it really is doing a fine service getting people interested in fitness and a good (rare) gym/box does have good trainers and care. I do have an issue with CrossFitters, though. In general, they tend to be very arrogant, close minded, and lack knowledge. They create the douchebag image themselves and live up to it in many instances. The attitude is partially what makes it dangerous, especially when it is the owners and trainers that have it. If they understood that they are not doing any revolutionary and just selling it under a trademark name, they may not feel so high on the horse and enjoy a better image.
