Toxic masculinity is the cause of this particular problem. Social conditioning and ridiculous expectations attached to 'gender' are also the problem. Invasive hormonal treatment - the effects of which are yet to be determined - are a pretty bloody drastic 'solution', and arguably not a solution at all. But there's no wonder effeminate men feel more comfortable in a woman's identity. Society simply offers such men no place at all as 'real' men. It's that assumption that needs to be challenged.
Being 'hormonal, emotional, hysterical', (add stupid, unsubstantiated, sexist rhetoric ad nauseum), is not a marker of womanhood. Had those sorts of views of women been expressed just five short years ago, they would have been laughed out of town as the antediluvian bigotry and sexist BS they are.
A friend of mine is suffering appalling menopausal symptoms, including migraines that wipe her out for three days at a time, and is unable to get access to HRT. You know. That specific therapy designed to relieve the real experience and related suffering of actual women. But women's suffering can go hang, while medical science panders to men's social hang-ups. It's staggering. And in the meantime, the left-wing (ha!) press capitulates to The Ideology and denigrates anyone who dares raise reasonable questions.
You know what? Despite the imbalance between so-called left- and right-wing press I sincerely hope the Guardian actually does go bust. They now don't even resemble any definition of 'left' I've ever recognised, and the left/right distinction is increasingly meaningless anyway.
