Ok I'll take the bait one more time. I don't care if someone trains by kicking steel poles. Move... In....
A circular attack focuses all the power at the end of the limb. Much like swinging a bat. The damage caused by getting hit higher up on the weapon, in this case a leg, is not even half of what would be caused by getting hit at the end of that weapon. I'd rather miss my technique and get hit by the upper thigh than get hit by that shin trained by kicking hard objects.
Aikido trains to enter in, blend and neutralize like any other circular attack. Questioning the ability of them to do so seems sort of disrespectful. After all, even with Krav Maga I was trained to enter in to an attack like that and take what little remaining balance the opponent has left. Honestly when I trained Aikido my Sensei told me that in a situation like that, just step in and take their balance much like I was taught in Krav Maga.
As for seeing Aikido raw and ins unscripted... Not gonna happen. The philosophy of the style is that it is used for peace. No Aikidoka is going to go out and join the UFC. Aikido wouldn't even be very useful in UFC because small joint manipulation is illegal in the cage.
If you want to see it unscripted, go to an accredited dojo and take a few classes. My Sensei had us sparring after our first class. No script. Just 2 or more people coming at you and the rest of the class watching and giving pointers on how to apply the techniques you've learned.
Demonstrations in any style can be and usually are choreographed to get the most spectacular show possible. It doesn't mean they can't use this stuff if they're forced to defend themselves. And it's effective. Heck one of our high ranking students didn't take a fall right after being thrown by my sensei and broke her collarbone on a mat. It made both of them feel horrible, but that's why you don't see Aikidoka throwing random people like that all the time, you can seriously hurt someone very easily. All it takes is a mistake on either end and it's hospital time for the poor guy on the ground.
So, moral of the story is. Stop asking questions like this and go take a class or two. I guarantee you'll learn more in two or three classes than asking questions like this on the forum.
