My bad about GSP and Kempo, I got mixed up when typing that. Even still, he doesn't fight like any kyokushin guy I've seen. You can see the background in his kicks, but not in his stance or his use of the jab or his wrestling. His footwork is there too, but most of his success came with his jab and double leg. Hence, him being called a boxer and a wrestler. And no one said anything about katas or that being what people fight like. Liddell I could see looking more like it, but people talk about him having that as his background all the time. I don't know any boxer that wants to claim Chuck is a boxer, most of them hate his upper body positioning, the fact that he keeps his chin up, where he holds his arms and how much he got hit. And again, punching is only a small portion of boxing. There's the stance, the footwork, the weight shifting, the movement of the hip joints, measuring range, creating openings, positioning your body and manipulating your opponent's perception of distance and your position, head movement and then there's actually punching.
Again, boxing is the only art that incorporates only striking with the hands. That's why it's used to describe that specific skill set. Knowing how to punch is maybe 20% of boxing. Calling someone's boxing skills punching ignores the other 80%, which is why no one calls it that. Don't change the context of the discussion, we aren't talking about street fighting. We're talking about MMA. And again, if you only wanna focus on the punching techniques you're missing the bigger picture. Boxing absolutely has the best punching techniques, but more importantly it contains the best information on how to land those punches and not be hit in return. You won't find it to the same extent in any other martial art. Guys roll shots all the time in MMA, and saying you can't is one of the biggest myths in the sport. If a guy knows WHEN to roll, you aren't gonna be able to clinch him or knee him because he'll be rolling in response to a different attack you're already attempting. Guys roll and slip every single event, and not knowing how to is a huge liability. You don't go to karate to do that, just ask Machida. Also, boxing is always considered a western sport but it's more of a global sport. The best boxers in the world aren't even coming from the U.S. anymore. They're coming from Cuba and Eastern bloc countries. MMA is still a gloved sport and no good boxing trainer teaches blocking as their main method of defense anyway. I'm not saying boxing is the best striking art (though I believe boxing fundamentals provide the best base for any striker in MMA), just that it's the best for learning how to use your hands.
I really can't argue with this last paragraph because I get the impression you feel personally insulted by these things and I haven't had the same experience of people looking to discredit martial arts. Everyone I talk to appreciates Pettis, Silva's, Bendo's and whoever elses TKD skills. Everyone appreciates Machida's karate skills.
Remember, the issue is that people are claiming fighter's learned certain moves in arts they never studied. I can promise you there is no JJ coach at Jackson's. However, I can also promise you that there ARE boxing and wrestling coaches at tristar. You're belief is that saying these guys have good wrestling or boxing is the same as saying Jones is using JJ shoulder cranks. It doesn't hold up because GSP and Chuck actually did train wrestling and boxing (and saying they are good wrestlers and boxers only means they have good skills with their hands and takedowns anyway) but Jones never trained JJ. You're misunderstanding the use of the words. I'm sure there is some ethnocentrism in the fact that we use popular sports of our culture to describe skill sets, but there isn't really a better way to do it because there isn't another word to describe those things that most people will understand.
