The post is probably automatically flagged because it's a new user and he has been largely downvoted in his other comments.

You can vouch for it if you think the comment has its place here.

(edit I don't have the "vouch" option, so maybe the comment has been downvoted as well, but it doesn't appear grey to me so I'm not sure).
