@BeckyAMumsnet, thanks for your reply. If 'misgendering' someone means referring to them as their biological sex, or using pronouns reflecting their biological sex, and those posts are being deleted, then truth is being censored.
If a scientist were to take a blood sample or a cheek swab etc from IW today, those cells will show up as male. If, many hundreds of years after IW's death, archaeologists excavate his grave, the remains will show a male pelvis; forensic analysis of tooth enamel will confirm the body as male.
If IW were to be posting on here this evening and referring to himself as female, that would be his belief, if the rest of us post on here and refer to him as male, that is ours because many of us believe in the truth of scientific fact and that belief is now protected in law.
Do the guidelines need reviewing?
