I've heard enough from trans-activists to know that when someone identifies as a woman, for example, they do not have to adhere to any particular type of presentation, mode of dress, speech patterns, expectations of behavior, roles, life pathways, or anything else. They can pretty much do and act however they please while retaining their gender identity as a woman.
I am not sure that I understand your point. Are you saying that women (since the vast majority of women identify as women) should have to adhere to a particular type of presentation, mode of dress, speech patterns, expectations of behavior, roles, life pathways, or something else? And that it's wrong to think that they do not have to do that?
And that, if they won't adhere to a particular type of presentation etc., then they should not be allowed to retain their gender identity as women?
Does it mean that women shouldn't be allowed to retain their gender identity as women if, for instance, they wear trousers, cut their hair short, speak in a gruff voice, marry other women, are construction workers or don't sit down when peeing?
