I can't respond to your other comment because it's flagged, so I'll respond here. I think most people don't mind pedants. The comment got a handful of upvotes, so clearly on the whole the addition was appreciated.

This platform actively discourages downvoting, so a couple people out of hundreds or thousands of viewers deciding to upvote you doesn't mean that the addition was appreciated.
I thought you meant exactly what you said, and I meant exactly what I said, passion and all. Regardless of the community sanctions, I still mean it.
