Mollygo, intransigence especially among the elderly is a statistical fact.
It's true that public retreats ,that's to say 'toilets' to use the somewhat smelly word , are inadequate for women not to mention people with babies , toddlers, and disabled people who may have special needs for changing facilities .There ought to be adequate, even comfortable provision for all.
There is a special lack of moral support for trans people who are people who include mothers, carers, and disabled as their individual cases may be.
If 'public toilets' were adequate they would be comfortably and safely unigender and unisex like any decently managed hotel , hospital, retirement home, school. or restaurant.
