To answer your various points OP-
clearly there is a lot of hate for men wanting to be women not around here there isn’t. No hate. A strong desire to defend the rights and safety of women and girls, yes. No hate. In fact many gender critical transwomen are members here, support ‘our’ points of view, write letters and articles to national newspapers and participate in WPUK events and similar. We are not against transwomen. We are for the rights & safety of women and girls.
nothing about women becoming men. Do you also frown upon this or is it ok and for what reason? again, you’re starting from false assumptions, it’s not about frowning on anyone. There are quite a few posts and threads discussing concerns around transmen, specifically about teenage girls identifying as transgender, the high rate of co-morbidity of factors like autism and sexual abuse and the fact that a strict gender-affirmative model of counselling and support fails to address these; the posited phenomenon of Rapid Onset Gender Dysphoria - very similar to the well recognised phenomenon of ‘outbreaks’ of anorexia, self harming etc we see in teenage girls, and the overall well-being of transmen - infertility, potential for lifelong health problems caused by hormonal treatment - is a distinct feminist concern. Many of us are acutely aware that if we were X decades younger, we would easily have been swayed by transgender ideology and have been vulnerable to taking life changing decisions that could have left us physically scarred and infertile, when in fact we were simply struggling with puberty and how the world treats women.
surely if you ignore transmen and just allow them to be men then the whole gender argument against transwomen is that much weaker again you’re coming at this from a false position on multiple fronts - firstly, generally feminists are not ignoring transmen (TRAs often seem to, shouting about transwomen rather than transgender people, though) - secondly it’s not about disallowing anyone to ‘be’ anything (if you mean dress, present, identify how they feel works best for them, in fact the opposite - break down those gender stereotype walls!), nor is this a ‘gender argument against transwomen’ - see my answer to your first question. So honestly I don’t know how to answer this point as it makes so many incorrect assumptions. But as others have already explained, one of the main concerns of feminists about transgender ideology is the threat to the rights and safety of women and girls, specifically the provision of sex-segregated female-only spaces, posed by gender self-identification of males. Clearly, transmen do not pose this threat to women.
