After the consultation, and Britain following the human rights law of Malta and Colombia, everyone will move on.
The use of precedent in implementing transgender policies seems key, both in sport and elsewhere.
In most interviews I have heard by those advocating for self-id in changes for the GRA (for example) the list of countries who have already done so seems always referenced.
But we don't in other areas of UK legislation always use this as justification.
By way of example,
(from Wikipedia)
"The only countries with permissive gun legislation are: Albania, Austria, Chad, Republic of Congo, Honduras, Micronesia, Namibia, Nigeria, Pakistan, Philippines, Senegal, Tanzania, the United States, Yemen and Zambia, although several other countries like Canada and the Czech Republic, despite theoretically being restrictive, are shall-issue countries."
Yet despite Donald Trump's recent suggestion, we don't have permissive gun laws in the UK.
NB I am illustrating a principle, not comparing those advocating for for transgender rights to those who support the NRA!
