“she voices her disagreement but does not explain what she thinks, so I am not able to respond to her concerns.”
False. You often say you would love to respond but you never do.
I used to answer you very clearly and extensively and you would rewrite my comment and distort my question. Sometimes responding to a totally different point or none at all. You would accuse me of saying things I never said, deny things you said or just plain not respond. So why in the world should I bother.
