The survey is titled:
Tell us about why single sex services are important to you personally
Not "tell us why you think single sex services are unimportant or should be dismantled".
The organisation is called sex matters not "gender identity matters and sex is irrelevant".
There are plenty of well funded and prominent organisations out there, producing surveys that are biased to centre people with a penis getting whatever they want all of the time.
This organisation is small and likely run by volunteers who shouldn't be expected to sift through a load of gender woo claptrap comments in order to do their quite specific research.
