I think you misunderstanding Budo spirit with fighting spirit.O sensei could talk a lot, however when he presented the techniques, it was very clear, that martial principles were present in every moment. It was not a case in this seminar.
I understood you attended one two hours class of that seminar?
I understood that you didn't train with Endo for about 15 years?
I understood that you didn't have an idea of the goals of the exercises you practiced?
I understood you didn't work with nage and uke who were familiar with those exercises and there goals?
I understood uke on the contrary were overreacting and were much too cooperative.
I understood the long explanations didn't tell you something?
I understood you still have to grip to handel your partner/attacker?
Hey, come on.
Is Matthias Claudius known in the US? He did a famous german evening song I have to think of. One verse of it:
Do you see the moon up there?
You can only see half of it,
all the same, it is round and beautiful.
The same goes for many things
that we laugh at without hesitation,
just because our eyes don't see them.
Thank you for your questions!
