I'm rather afraid I'm going to get shouted at for posting here when I don't have a SN child; but I do see the threads (usually look at MN via 'last hour' view so you see a bit of story) and I found I wanted to say something.
MN has actually been very educational for me in terms of SN; which is basically thanks to you lot. I wasn't completely unaware - I have a cousin about 10 years younger who will be in assisted living (not sure what you call it) all her life - but you do give a very different perspective, and maybe a glimpse into what a nightmare dealing with the services intended to support you can be.
I'm pretty sure I'm not unique in having my understanding improved, and part of that is through reading the threads which you are talking about. On the bus one, lots of people did change their mind once they realised what the OP meant. I know you think they should have realised earlier - but people do read things quickly, from their own vantage point etc; it isn't necessarily ill intended. And that (the change of mind, the increased understanding) has to be a good thing, doesn't it?
I'm not for a moment justifying the nasty posts (the restaurant one for example) but that poster seemed to me to be getting completely shot down in flames (unless things changed after I read the thread) - again, isn't that good? someone who maybe thought like that, reading the thread, could realise how out of order they were being?
It must be pretty horrible to feel the prejudices etc but please, if you can bear it, don't stop responding, don't retreat to boards which are just for SN parents, keep helping those of us who haven't 'had' to understand what it is like, to get a bit more of a clue.
Thanks all of you.
