Since 2015, TRAs have flip flopped between 'sex and gender are separate concepts' and 'sex is a pretty meaningless/unhelpful construct as it's difficult to define and/or determine- so we ought to ignore it in favour of gender'.
Recently, we have seen a resurgence of the latter position, as demonstrated in the current Peggie v Fife NHS Board.
Counter arguments based on gametes aren't particularly accessible to the general public m, whereas references to fertility are.
In developed countries, the infertility rate is approximately 9% of males and 11% of females. Of the 9% infertile males and 11% infertile females, 0% are infertile for reasons pertaining to their sex being difficult to determine.
People know that it must be vanishingly rare not to know whether a condom or the pill is a suitable contraceptive method for oneself and to suggest otherwise is glaringly bat shit crazy. These arguments link to concrete experience/action, whilst conversation about hormone levels and chromosomes refer to factors that are typically unconfirmed for a given person.
People with a much sharper mind than me (like Naomi Cunningham) will have good reason for not drawing upon fertility to evidence sex is not nebulous. This post is to try and understand why this is.
Can anyone help?
