If you didn’t read the original post, stop and go back and read it–because in context, there’s no other way to read it except as “14 or younger”. I know it’s super-fun to try to play “gotcha”, but it’s kind of pathetic to do it without clicking on a link to the post. But since it’s too much bother, let me quote Budget Rapist Cadet from his post #44:
She’s not 16, she’s not 15, if she’s 17 or older, the thread doesn’t make sense, ergo she’s charitably 14.
