Qiauchu_Yuan is a mathematician and I’m quite sure he’s familiar with the “current official math position”. I don’t think your presentation of it is wrong, but I think it’s unnecessary in this particular discussion :-). When you say there are no real numbers between 0.999… and 1 and therefore the two are equal, you are not disagreeing with QY but with a hypothetical person he’s postulated, whose knowledge of mathematics is much less than either yours or QY’s.
