Wow - careful, you're starting to sound a little threatened and petty
Clearly you need to step out of your "planet" and spend more time with kids, they can do some amazing things. Many elite athletes began training at age 3-5, it's the beginning of the journey. So what if it improves motor skills, it also fosters interest in MA and helps them with basic skills, language, respect and history. My preschooler adores her classes and can do a roundhouse kick with far more accuracy and flexibility than a couple of newcomers to my adult class! This is why they have poom instead of dan. Kids learn far faster than "we" do and can pick up things with far more accuracy.
See I think you have to really define what you are teaching to 4-6 year olds. I personally teach this age groups (affectionately called "little ninjas") and we call everything we do pre-taekwondo. They don't learn forms or self-defense (in the traditional sense). Instead they spend about 6 months on three different kicks, strikes, blocks, and stances and then another set for another 6 months and so on for two years. They also learn "self-defense" such as knowing your home phone number, knowing that adults will not ask a child for help (ex: looking for a puppy), etc. Our program is designed so that after at least two years these kids are ready to go into the real Taekwondo class. The Little ninjas are awarded belts, and even a little ninja black belt, but this is not recognized as any sort of Taekwondo rank, it is not a poom and it definitely doesn't get a Kukkiwon certificate. A LN black belt just means you are ready to be a REAL white belt. I have found this to be a great system for kids because by the time they are 12 (and now a poom black belt) they have been doing basic techniques for 8 years, so they are going to be better off then a kid who starts at 10. But at the same time I don't feel like I am sacrificing my art by promoting a 5 year old in the same way I would promote a 25 year old.
Everyone has to find what works for them though.
