It's kind of silly for someone to wonder why people are "responding to the letter" in the way that they are. OF course they are not, they are responding to what other people say about the letter and to the responses to those responses and on and on. The letter starts a conversation which develops. Getting all righteous about people being off topic so you can say what you want, (in this instance that there is no basis for drawing conculsions) about anything you want, just reinforces the point of saying that in this case the woman who said this would, statistically speaking, in all likelihoood be very happy to draw consclusions if she had the same amount of information from a woman making a similar complaint about a man.
