The point is whether your aikido skills (or other martial training) would stand up to being physically trapped with a stronger, more aggressive, clinically insane predator as shown in the clip.
Is this a joke?
All training aside, you would either prevail or not.
If you don't have that understanding, then whatever martial art you have been training no matter how th3 d34dly you think it is, is worthless.
Fantasy "pressure testing" and a few rounds of sparring and rolling with other amateures does not make anyone ready to "stand up to" that.
Living in a mental world of fear and aggression, and training based of that world view is just as much fantasy role playing as anything else.
