So, Dan, I am asking why. Useless for what? You say
everything every Japanese teacher is teaching is all but useless? That is quite a statement.
That's not what he said, or really even close to it. What he said was, "I
have never read
anything really meaningful from Shioda or any other Japanese guy about what they do. Everything I have seen so far
from a Japanese teacher is all but useless." [emphasis mine] That is, he was a)speaking from his own experience and b)speaking of writings, not of teaching. I hope you see the difference.
