Yeah. I know. I'm not the one confused.
This means he's at least first dan. He could be 2nd dan, 3rd dan, or higher. He hasn't explicitely said he's 1st dan.
I'm mainly picking nits here.
There is no such thing as WTF taekwondo. Never has been.
The WT (it's not even called the WTF anymore) is purely a sports governing body. It has no curriculum, no schools, and awards no rank. It supervises competition. That is all.
I'm going to disagree with this. For one, even though the name has changed from WTF to WT, it's still the same organization, and organizations tend to get called their old name. For example, one of the branches of the IT department has changed from "Information Assurance" to "Cybersecurity" about 5 years ago, and we still call them "IA". There's also the joke of the "ATM Machine" (as everyone calls them), which is the Automatic Teller Machine Machine if you actually follow the logic.
If someone says WTF TKD, you know exactly what they're talking about, even if WT is the more correct term.
With that said, there is a heavy integration between KKW and WT. They have a symbiotic relationship with each other. The KKW schools teach techniques and tactics to use in WT sparring, and the WT poomse competition rules focus on forms learned in the KKW curriculum.
If the KKW decided all of a sudden, instead of the Taegeuks, we're going to do the Skribs pattern of forms (which, if I may use my completely unbiased opinion, would be by far the best forms ever used in any martial art), then the WT rules would change to accommodate the Skribs forms in addition to or instead of the Taegeuks.
Alternatively, if WT changes their sparring rules, KKW schools adapt their sparring training to comply with the new rules, and to teach the strategies that open up as a result of the rule change.
Similarly, if one organization just quit, the other would take a serious blow and need to regroup. If the KKW went away and all of the schools had to decide whether to re-register under ATA or ITF, create their own new organization, or run unaffiliated, then the WT would need to look at reaching out to the other organizations. It would be a significant shift in their target audience.
And if the WT suddenly decided to stop governing tournaments, then the KKW schools would be training in vain for competitions that do not exist (at least as far as the competition-related training they do). The KKW would then need to govern sparring rules or leave the sparring curriculum up to the local masters, or would need to find another organization to run tournaments to complement the KKW curriculum.
However you look at it, yes they are two different organizations, but they're two different organizations like the Navy and Marines are two different organizations. Technically separate, yet integrated and dependent on each other.
