I did face a barrage, DebsCee, which increased as I defended myself - and when people have come onto the thread and seen the very mild words I wrote that pressed weejie's buttons, there's been surprise at the strength of the barrage.
Here's my take on what happened: I responded to the OP sensitively, allowing for the fact that I knew nothing about her motives, level of knowledge, experience or feelings. I have already said she could have been a student gathering info (this happens on MN from time to time). She may not have considered breastfeeding as an option - there's a thread going today from a mother of 3, who did not breastfeed her first 2 as she just never considered it, didn't even cross her radar - and may not have even thought of breastmilk as 'organic'.
Weejie read my post and thought 'but I can't breastfeed - telling me breastmilk is organic makes me feel upset'...projecting her own experience and response onto the OP, who as I have said, had not shared any info with us at all.
This is a risk with mumsnet. You are not just talking to the OP, but to every Tom Dick and Harriet who's reading it, with their own issues and experience. It's a public stage.
The onus is on all of us as readers and posters to remember that, and to judge how to respond....I made a judgement when I responded to the OP, knowing full well that someone somewhere might not like it very much, but my focus was the OP so I 'risked' it. I think it is worth the risk. Not mentioning breastfeeding at all would have been unnecessarily precious (if the OP had given any info to suggest she did not want bf mentioned, then of course I would have respected that).
