Great, then all he needs to do to support his claim is quote my exact words in context and show how they demonstrate a lack of understanding. Easy-Peezy-Lemon-Squeasy. He sounds like he is just one step away ... except that he just revealed that his confusion, or his "observation" as you put it, is based on his lack of reading comprehension, so he might have to search further for some other "observation."
Perhaps you can help him out. Explain to him where I have erred on this topic in the past. Just make sure to actually quote me instead of claiming that I wrote something that I did not (as you are inclined to do).
