Cote I completely agree with your point about individual preferences vs groups, this long and well thought out post(from BuffytheReasonableFeminist) on another thread is spot on in my opinion
"I think the problem MNHQ have is the assumption that these two perspectives on sex and gender can exist side-by-side in a sort of 'you have your view, I've got mine, let's just respect that and be polite to one another'.
When in fact they are incommensurable. A venn diagram of two circles that don't overlap at all. You cannot at the same time believe women are women because they have been born with particular physiological arrangements that have a very precisely defined meaning in our society, said meaning leading to socialisation, and at the same time believe that a woman is a person who identifies with the gender identity woman regardless of physiology and socialisation. The two are different cause and effect pathways (if you like) and because they are grand social theories about sex and gender, you can't say that one person experiences one and another person another, because the whole point is that they seek to explain these over-arching processes, not individual experiences. In fact each version can easily can explain the other 'side's' beliefs in the terms of their own theory. It's just that these explanations cause deadly offence.
In other words, if you believe one is true, whichever one, then the other one can't be true, because your acceptance of one explanation of what womanhood is, necessarily means that the other explanation, whichever one, isn't actually what happens. If you believe in gender identity, then women with female physiology who call themselves women because of that actually have a 'female gender identity' and are cis (deadly offence to people who don't believe in gender identity). If you don't believe in it, people who are trans are in fact the biological sex they've always been, and simply identify more with the stereotype of the opposite sex, so they adopt the markers of said opposite sex (deadly offence to people who believe in innate gender identity).
That's the underlying reason why it's so very difficult to talk about it. It's not about pronouns, or politeness, it's about the unfortunate fact that stating one's sincerely held belief in how the world works, and thus how one has experienced it, is in itself offensive to those who hold the opposite view. That's why MNHQ will always struggle with it, because they're trying to occupy a middle/neutral ground that doesn't actually exist, when you dig below the surface."
