I was so surprised by the Guardian article (shouldn't have been, probably 😑)
For years, people with a disability have explained that since the disabled toilets are often rare, it is vital that they are quickly accessible - I am not only talking about the UK but it is a problem in other countries, too, and especially older buildings don't always have one. It is very strange to read that disability campaigners now openly invite trans people (mostly men) into these places, and I see another forced teaming going on since the SC ruling (first the tm, and the masculine looking women, now the people with a disability?). It is the way they are speaking about discrimination.
The examples where someone is both, trans and with a disability, they can of course use them on the basis of the disability.
The background that if you class neurodiversity as disability (not everyone does), which tunes in with a higher likelihood to be captured by trans philosophy due to the feeling of not fitting in, is also not properly explained, though The Guardian knows about the new screening for autism etc at Gender Dysphoria clinics.
The other reason for a connection between them both are physical disabilities or at least problems brought on by cross-sex hormones, blockers and surgery.
Both of these backgrounds are ignored by the article, too, though these are two main points why trans and disability can overlap. The way this is written reads as if there was a magical connection out of nowhere.
