It has been asked here about questions with "my $X$ said", where $X$ is more general than "teacher". It seems the consensus is that this is irrelevant to the question. The point of the post I linked, I think, was to address the questions themselves: should they stay or not.
My purpose with this post is different. I feel like the case of "my teacher said (...)" very often leads to rudeness and/or a misrepresentation of the work of a teacher (see here for examples in the comments). The teacher being identifiable or not, it is still a disservice to his work, and it is almost always irrelevant to the question itself. We could just delete that part and the question would hold ground by itself.
My question is: what is your take on this? Do you agree?
And more practically: Can I edit away such "context"? Or would this be too intrusive to the post?
