At what point do people have to comply with a person's philosophical belief based on post modernist theory that they are what they say they are?
Because when a male person states that they are a 'woman', they are doing either of two things. They are either rejecting being a 'man' which is based on their own stereotypes for what defines a 'man', or they are enforcing their belief of what defines a woman. The latter is misogynistic, because they are defining women and girls to be something other than female. All based on their own philosophical belief. When the material reality is that the only people who can be women and girls are female people, unless that philosophical belief is wedged into the definition.
And it is only ever a philosophical belief.
A male person can only ever live their own interpretation of how a female person, a woman, lives their life. Those male people calling themselves women are only ever male people calling themselves women. They are never experiencing life as a female, shaped by a lifetime of being a female dealing with living life in a body formed around the production of large gametes even if those gametes are not produced.
No person living in the UK is required to comply with someone's philosophical belief. To attempt to shame people for not complying with that philosophical belief is both totalitarian and authoritarian.
