You know what, I'm suprised that the OP was the parent of a SN child. Not because everything in the OP was mean or untrue. There is some truth to what she was saying. There are the people, on here and in RL, who do make everything a competition about who's got it hardest. There are the people who lie or exaggerate to get more sympathy. There are the people who think it gives them an excuse for something.
But I was very surprised to hear a parent of a SN child talking in such a derogatory way about the 'SN police', as though every parent of a SN child is lumped in together and some kind of different species. SN posters are not one huge, homogenous mass.
Even with posters that I'm not so keen on, I can't imagine turning on parents from the SN board en mass like she did, deliberately exposing 'parents of SN children' on the most public busy board rather than choosing to go onto the SN board and do it here, is because it's almost trying to turn people against them/ us.
When you have a child with SN, it becomes an entrenched part of your identity. And yes, I do sometimes find myself thinking - 'I wish I had your 'problems'' - I don't think I ever say it, even if some do - but I think that those that may say some of the things that she put do it because SN is the centre of what they are. As a parent of a child with SN, how can she have no sympathy with that? So, to effectively ask a high proportion of MN-ers to come and mock the special needs tops trumps and martyr mums seems to me to be a pretty cruel thing to do, even if some of the general points about competitiveness etc. are valid.
The post was a snipe at a collective group of people who are all dealing with their lives in different ways. Some posters' behaviour might be questionable but to have a pop at a whole group on the basis that they are all SN mums is unfair.
It is more about how some people, as individuals, post than about SN mums as a group and I think what she said is unhelpful and unfair, as it portrays a whole group as a bunch of whingers. At times for me, everything becomes about autism. I can't help it. For some, their whole identity is bound up in being the parent of a SN child and, while that's not healthy, neither is it healthy to hold them up for censure for it. So I think the OP was being unwise and unpleasant in how she addressed the issues bugging her.
