Do you think O-sensei would have been sweet and nice to Stuart? Or do you think he would have broken both his arms?...
Not posting too seriously
No, I don't believe O-sensei would have let words provoke him to physical violence.
It seems there are better ways to handle Stuart than by the" way of the fist".
In addition, I have to agree with Paul. Aikido is a part of a larger picture. Even O-sensei was familiar with "other" arts as well.
Yours in Aikihood
