Well, I always say "let's try" or, in some cases, "bring it on".
That's how things work in the (my) martial arts world. Your world is a different one and you don't understand mine.
Demetrio, the world you describe is the same as the one I know in budo. It's strange that Graham completely rejects it. Ueshiba had your same attitude, too. Mochizuki. Tomiki, Saito, Shioda. Every real budo man (or woman) I've known has had that attitude. I wonder why Graham does not share it since he is an aikido man.
