I'm not even too bothered about the results of the survey, but just want to post as it seems every few weeks there is some totally nonsensical grad student survey published, and they all seemed to be funded by the ESRC.
My worry is that all of these will be archived in Libraries and at some time in the future research will then prove that we were all trans and have a legal gende.
