Recently, Twitter has been arbitrarily banning women for voicing concerns about the impact of self-identification (i.e. the notion that self-identifying as a woman is sufficient for being a woman) upon women, and in particular, concerns about the impact upon women's spaces (e.g. refuges, rape crisis centres, lesbian events), women's sports given the physical advantages a male physique naturally confers, and the rights of women to speak freely in general without professional and personal recriminations.
