Like a pp said, many times when a mom asks about weaning it is really a cry for help.
In the thread that most of us seem to be thinking about, I think the people who responded generally did a good job of gently asking for more information so they could help.
I think part of the problem is that there is SO much misinformation out there about breastfeeding (and other parenting issues, but breastfeeding especially) that you just can't assume that any poster has had access to the information, support and resources we have.
So, I think that reinforces not only the notion that it's OK to ask those probing questions when someone asks about weaning (even though it can be quite annoying to those who KNOW they are already informed), but it's also OK for those people who don't completely understand the philosophy of this board (not just this forum, but MDC) to post questions which may seem a little off, so that they can get the knowledge, support and resources we all have access to.
There are many, many mamas out there who go through dark spells of parenting completely alone. I really feel strongly it is wrong to judge them. I strongly believe in CLW. But I also STRONGLY believe that many women are NOT in a situation that makes CLW conducive. Some more than others. And we need to understand and realize that fact.
I think gentle, probing questions and respectful, supportive information have changed the thought processes of MANY mamas on MDC. I hope that continues.
