Karen White doesn't have a GRC and apart from dressing in feminine clothes and wearing make-up, there's no other commitment to transitioning.
White was jailed for various crimes including violent rape and sexual assault in the male estate but began transitioning in jail. White attended various support groups and became aware of their 'rights'. White approached a case review board that considers the needs of transgender prisoners (prison governors, psychologists) and made their case for transfer.
White was transferred to a women's estate at the very first level (so no chance to examine offending reports and history, no consideration of reports made by those who'd met White and stated them as being "manipulative and controlling"). White went on to repeat his abusive, predatory pattern and raped 3 different women.
Despite being legally a man at the time, the Ministry of Justice decides to be ahead of the law and placed White's feelings above the safety of women.
Does having a GRC alter male pattern violence? Nope. But at least one would hope that applying for a GRC would 'oust' any man who's using the GRC for nefarious means.
Agencies across our civilised world are changing their Policies to be 'woke' and inclusive at the cost of basic safeguarding. Fact.
Self ID is a legal drive to do away with all aspects of GRC due process. It will be abused, it IS being abused and women are very very frightened. Your DH won't grasp this because he's a reasonable and decent man. But there are women for when time began who know the lengths that men will go to
to hunt their prey. Self ID is the green light for these predatory men.
NB - I've not mentioned Trans Women here have I... yet I would be deemed as transphobic for holding these views.
