That is just your perception. Any sport that has subjective judging based on human decision making is going to have perceptions of credibility. I think there are sports out there who are suffering a lot more with credibility issues (cycling for example). Skating is a small fish in a big pond of sport which the reality is most people couldn't care less about and are probably caring less about. Whilst judging perception is one factor, it is not the only factor which many people have put forward other ideas and theories.
