I do think it's a bit crap - in general, it's women who need a smear test. Plain English does mean making sure the message is understood - because it's a massively MASSIVELY important message.
Women between the ages of 25-64 should have a smear test.
That's clear and will be universally understood by the majority.
Trans men may need a smear test too, but they should have this covered as part of their medical care around transitioning. Unless they are not accessing any medical care around transitioning. Which is another question.
Gender non-conforming people, or non-binary, or gender queer - they should also understand that they are classed as "women" in terms of biology, even if they do not wish to be referred to that way. After all, they've rejected it as an identity but they know that biologically their body is not male. Again, if this is particularly distressing then they should be under medical care for the dysmorphia, as above.
Campaign for more services for trans/gender NC/non binary etc. They should not be excluded from these services if they won't attend "women's health" clinics etc.
And what a crock of shite that they revised the "women" out for "people with a cervix" but didn't change the men to people with prostates AT THE SAME TIME. It's not a tin-foil hat conspiracy to think women are being treated differently - again, like always.
