He interpreted me saying that two statements were the same statement as saying that they were logically equivalent rather than two parts of one whole. An understandable error but one that had the effect of completely changing the point. I corrected him three times, and he continued to insist that my position was not what it was. Meanwhile, he also accused me of misrepresenting his position, but refused to clarify when I asked, and continued to insist that I was deliberately misrepresenting him.
So, as you can see, your memory is faulty.
But seriously, I think it was pretty low.
