While she may have said something that wasn't necessary, or was rude (I'm not saying I think it was or wasn't, just going by the responses), she didn't say anything idiotic. Idiotic would be to say "Awwww, a cow died" or something similarly ridiculous.
And Diane, I realize you're older than both myself and Amy, but age does not always equal endless intelligence. You recently said a lot of things about Amy being immature in the adult section. I chose not to say anything because you were simply talking about her behavior. Now here you call her an idiot, and I'd have to say that's no better than what you're berating her for. If she's immature for making her comment about the "dead horse" thread, then you're immature for calling her an idiot.
