I agree Barracker.
I'd also add that I see gender identity ideology as a collective madness that has gripped the psyche of the Western world - it isn't confined to people who identify as trans. Trans-identified people make visible a lot of the illogical, contradictory and sexist beliefs that most people hold about 'gender', and these beliefs are held at the deepest (unconscious) level.
Trans ideology clearly has a mystical appeal to whole swathes of society. It's no accident that so many people - from doctors to politicians to teachers to parents - have embraced it with a religious fervour. The psychologist Lisa Marchiano used Jung's concept of psychic epidemics to explain the current mania for trans, and you don't have to be a Jungian to find it very apt:
Having lived through both World Wars, Jung was aware of the dangers of what he termed “psychic epidemics.” He discussed the spontaneous manifestation of an archetype within collective life as indicative of a critical time during which there is a serious risk of a destructive psychic epidemic.
That is one of the non-trivial ways that transgenderism differs from transracialism - we aren't seeing huge numbers of people, especially young people, declaring themselves transracial. Clearly 'gender' manifests in psychic disruptions in a way that race doesn't, and archetypes around masculinity and femininity are probably the oldest ones in existence.
The concept (delusion) of having the freedom to 'choose' one's sex appeals to so many people on so many levels - feminists especially. Many women seem to find irresistible the idea that we could transcend our female biology by uncoupling it from the definition of 'woman' (and in fact denial of the importance of the sexed body underlay much of second-wave 'equality' feminism, and the notion that men and women are basically interchangeable is part of the reason feminists are now having such trouble getting women to grasp the dangers of doing away with sex-based protections).
Men who identify as women obviously see a freedom in what they fantasise their feminine ideal to be. Trans-identified women and girls are not wrong for imagining that identifying out of their sex (or attempting to) will offer them greater freedom and respect. And to everyone, gender identity ideology promises the ultimate freedom of the individual: the ability for the mind to triumph over the body and thus subordinate one of the immutable facts of our mammalian existence to the power of modern technology and the will. What I am saying that it isn't only trans-identified people who hold delusional beliefs about sex and gender. If it were, gender identity ideology could not have gotten the grip that it has on society.
Therefore I welcome trans-identified men who have come to a more grounded perspective speaking out and exposing the falsities of gender identity ideology. (However, I will not use female pronouns for them, and I won't refer to them by the Orwellian neologism 'transwoman'). I also don't see trans-identified people as fundamentally different from the rest of us. That is one of the big myths of trans doctrine - that some people are born 'cis' and some are born 'trans'. No. There are no trans and cis people, just women and men. This is why I always use 'trans-identified', instead of 'trans' - to counter the notion that 'trans' is an inborn characteristic. AGP men creep me the fuck out, but again, I see them as sexually obsessive, narcissistic men - they aren't that different from other men of that ilk, they are just much more successful at hoodwinking people into indulging their behaviour (which is why I think a lot of non-AGP, garden variety predators are now claiming 'transwoman' identity too, but that's another issue).
That said, I am uncomfortable with the way women police themselves and other women in the presence of trans-identified men. It prevents us from speaking as freely and honestly as we might because we are scared of hurting feelings. It does worry me that WPUK is centring the voices of TIMs to the extent that they are. As if they just automatically assume the organisation will lack authority and credence without male voices. I was dismayed to hear Julia Long was booed (or maybe tut-tutted?) for stating very basic facts at the last WPUK meeting.
Sorry, that was a bit rambling. TL; DR: gender identity ideology is a collective madness, so all critical voices, including those of trans-identified men, apply in this landscape. But women's activism on this issue needs to be clear about centring women and promoting their voices.
