I appreciated tel's comment. It contributed something to the conversation that was constructive and informative for anyone who didn't know the usage difference. I tend to skim over that kind of comment quickly if it's something I already know, just like I would for any other content I was already familiar with. Your angry comment, on the other hand really was distracting. If you have a problem helping out people, even non-native speakers, then don't do it yourself.
