This is a TAAT, sorry. Actually it's about many, many threads, but the one that triggered it was the current one about being annoyed at people faffing at the front of supermarket queues.
It's such a common occurrence on threads like this for people to point out that the situation the OP objects to can often be caused by disabilities. Cue lots of irritable posts from lots of posters that 'we weren't talking about people with disabilities' and 'of course I don't mean people with disabilities' etc. Sometimes they're meant kindly, sometimes they're quite unpleasant (with talk of 'the professionally offended' and the like.
Sometimes it makes me want to scream that the world is NOT a place filled with "normal non-disabled people" and a few "disabled people" on the fringes. There are millions of people with disabilities in this world, all trying to go about their daily business. In fact, everybody in this world has a range of physical and mental capabilities - we are all on a continuum.
So, when people with disabilities post on a thread, please don't cut us off with a breezy 'oh we don't mean you'. Our experiences are just as valid as anyone else's, we are part of the general public milling around that you meet every day (though you may have no idea about our disabilities). We are not 'extreme cases' or 'unlikely scenarios'. MN should be a place for everyone, not just those above a certain cut-off point on the capability continuum.
AIBU?
