I agree Draco wasn’t moving the plot forward much by himself, but I was going with the focus of the comment you were replying to, in which this is Harry moving a part of the plot forward—the plot-point being that people like Draco can have their beliefs challenged and learn, that people are products of their environment to varying degrees but that doesn’t mean you should ignore them, and also showing off the various ways people react to differences in belief.
That is, while this doesn’t have huge effects in story, though I disagree that it has none, it was a core plot point with a specific message it was trying to extol. And so Harry pushing this through does affect things.
