@Grenadier Apologies, didnt see the notice until i posted this. If it breaks any rules.
I dispute who is a expert and who determines that. I dont dispute some people know more than me, but a arbitary status you can give yourself really doesnt matter to me, i still want a explination of said points. Also "experts" can be wrong, everyone is fallible. Edit: The term expert itself is partly subjective to the knowledge of a subject by all parties. Eg one can be a expert in alegebra because they know the basics to one who doesnt know it.
I picked this part specifically. You don't know enough to determine who is an expert and who isn't. I don't just mean in general. I mean that you, specifically, don't have the first-hand knowledge of martial arts training enough to make that determination. You hide behind articles and supposed logic, but it's all excuses to keep yourself from training. You've deluded yourself into thinking that training is optional to build skill.
I remember the very first post you made on this site, where you said the hook punch is a bad punch because you can hurt your hand. This was based on you trying to learn how to do a hook punch yourself, doing it wrong and hurting yourself. Rather than seek training on how to hook punch successfully, you just said it was a bad punch in the article you wrote on the various types of punches. As far as I can tell, this is the ceiling you can get by training on your own. It's something we've been saying for years to you now, but you're still too stubborn to let anyone else try and teach you how to fight.
Most people who teach martial arts did not give themselves an arbitrary status. Most people who teach martial arts have decades of experience and certifications from their instructor or their organization, proving they are qualified to teach what they are teaching. Most people who teach martial arts have learned how to teach martial arts, and what it takes for their students to be successful. To quote the Farmer's Insurance commercial, we know a thing or two, because we've seen a thing or two. Your experience in martial arts training is so lacking, you don't even know what you don't know.
Now, please don't take this as an insult. I'm just trying to help you humble yourself enough that you can actually go and get training. I think a lot of us on this forum have. You seem to love the idea of martial arts, based on your post count and the length you put into each of them. But you gotta train. MartialTalk, YouTube, and Google aren't enough. You gotta put your feet on the mat and the gloves on your hands, you've got to square off against people that are better than you, you've got to have someone who can look at your technique and tell you how you can do it faster, stronger, and safer.
Even I, as a 3rd degree black belt, still learn things from my Master, like tips on how to increase the power of some of my kicks. A lot of these are things I probably wouldn't have learned by horsing around with my friends. I've got 10 years of being trained, and I still need the advice of people with more expertise than me. Are there some people who are higher rank than me who don't know as much as me? Yes. Are there some people running schools that aren't very good teachers or martial artists? Yes. But the existence of bad schools doesn't warrant a blanket excuse that you shouldn't train martial arts because the teachers are bad.
It's an excuse, either borne of arrogance or laziness, or possibly both. Arrogance in that you think you're smarter than all of the experts. Laziness in that you don't want to actually train, and are quite happy just being a keyboard ninja. This excuse that the expert might not be that great is just an excuse that's holding you back. If you have as much passion for martial arts as your posts here suggest, then set aside your hubris and actually take classes. Learn enough that you know what you don't know, and then learn that as well.
I've got 10 years in TKD, 4 years in HKD, and 3 years of wrestling. I'm currently training TKD and HKD. I lament the fact that I don't have time in my schedule to also train boxing, wrestling, muay thai, wing chun, kali, judo, and bjj in addition to what I'm training now. I wish I had the opportunity to learn from as many experts as I could, so I could have as much knowledge, technique, and experience as I could possibly get. For you, I wish you would find one expert that you could trust enough to actually teach you.
As to the last part about algebra...you could still learn from someone who knows the basics better than you.
