Written word on a forum can easily be taken out of context.
I wasn't surprised Josephine became a little defensive, but to the above poster (sorry can't remember your name) who is a MH nurse, I am surprised you didn't pick up on that in the first place given your qualifications and instead said you felt "irked". Don't be offended, this is simply how it came across to me, reading. I'm sure you are good at what you do, but it's much harder to read a person with only their text to assess.
This is a sensitive subject, especially in light of the fact Josephine clearly wants another child but this isn't mutual with her OH at this time.
I think it may have been more constructive to explain that it's ok for people who have completed their families to post on a pregnancy test thread, because they want to help.
I do think everyone who has posted in a similar way, with similar opinion, has done so with good intentions. But I think because text is hard to read as it is meant by the person posting, it can cause friction. Some appreciate bluntness, I do myself, but some are more sensitive to this and so whilst they may appreciate honesty, when honesty is paired with bluntness it may be taken the wrong way.
I sent Josephine a PM in case she wanted to talk away from the thread.
I think all of your intentions come from a good place, but if everyone starts to get pissed off with each other then this will only lead to Josephine feeling alienated, which isn't what anyone here wants.
This post is meant with good intentions but it may well be read out of context. Apologies if it is
