"Almost nobody except X does Y." and "Z does Y, with Z != X" are consistent. Is your disagreement entirely due to the (possibly nil) distinction between "Almost nobody except X does Y" and "Almost nobody does Y -- Except X", which is how the article is worded? If so, at least one native English speaker will disagree.

The poster you're replying to seems to have more of an emphasis in how the "Wrong." parent was worded. There was no need to be that confrontational, when one is adding a point of information ("Z does Y, with Z != X") that is most likely consistent with the thread title, and with the article content.
