This is the first time I've had a chance to read this thread. Having considered all possible actions, my opinion, FWIW, is to treat the whole thing with the contempt it deserves, and ignore it. Did anyone ever take The Mirror seriously anyway? Yes, those involved have to respond, and some people are using it for their own ends, which is nothing new. For the rest of us, I suspect that if we keep quiet it will die a natural death, as many Mirror "stories" have in the past.
Now if that doesn't happen, then is the time to think again.
