I guess I'm wondering why the fact that people disagreed with those words and are posting about this disagreement is an issue that demands editing the original post?

You do make a good point about there being lots of things out there with which one disagrees :).

My thoughts behind wanting an edit are that because it's presented as a guide (not *the* guide or anything, but still, a useful how-to), and that the section in question is pretty near the start and so seems fairly significant, it seems too much like an endorsement to leave it as-is. I think that to remove it without comment runs the risk of making the concern invisible again, but just personally, I'm unhappy with a how-to sitting in a slash comm with that suggestion so prominent.

That it appeared in the first place has made for some really interesting discussion, though!
