I don't know who Carole Malone is [in case she's v famous I should add that I'm not in the UK].
I could google her I suppose but I prefer to read this piece with an open mind.
I think it's good. There's a nice underlying sense of 'Oh FFS' about it, but she also gives several examples, and she seems to have made sure she got all her names and dates right.
I like that she points out that single-sex toilets suit 99.5% of the population - that's a point that I regularly make when questioning the rationale for having to provide gender-neutral 'third' spaces for such a tiny percentage of the population.
