"The sheer dishonesty of editing a post without including a caveat speaks ill of that person, and I will no longer post to a thread on which he has posted."

I'm staying out of the argument. But I have to admit I do this all the time - usually without thinking about it. I reread a post and realize I've made grammatical or spelling errors or left out a sentence that connects two thoughts. If this were a more formal venue or if I were making extensive edits, I might include such a note.
