Some of us judge the worth of a comment based on what is said, not who said it. Except for appeals to authority, which are rarely necessary here outside of con staff and artists/authors, it doesn't matter who said what unless you wanted to judge the comment without reading it. Although it looks like the Anon you are replying to (which is not me) shares your opinion on identity and worth, trying to invalidate your comment, in part, based on who you are.
