If the LGBTQWTF hadn’t all been collapsed into one giant hole it might be easier to identify specific needs (eg there are some HIV positive gay men in their senior years who might benefit from on site viral load testing and there are some trans people who forget they transitioned and need support coming to terms with missing body parts, although that’s likely to affect people in higher dependency care than just supported housing).
I watched a lovely Netflix documentary about a senior lesbian couple who had been living together as ‘friends’ their whole adult lives and part of the process of moving into supported housing for them involved ‘coming out’ to family and finding a place where they would be free to be an open couple (iirc they even married after moving). It’s an absolute tear jerker of a film.
Manchester probably does have a higher than average proportion of LGB & T people so it likely makes sense in planning & social care terms.
