The man in that video spent 30 years in prison for kidnap, torture, rape and attempted murder, and is threatening violence to women now he's been released.
He's says he's a woman. Would you find it acceptable for him to use a women's refuge, be incarcerated in a women's prison, undress himself in a women's changing room, and so on, based on his self-declaration of womanhood? If yes, then you'd be indulging in a luxury belief.
