Beach I said in the context of an identity debate not all the time. I don't think those statements are transphobic as a rule, I can just imagine some contexts in which they could be. If you are saying they are labelled transphobic 100% of the time, then that is excessive.
dreamingbohemian I've been thinking about what you said here and I find it quite illuminating as to the arbitrary and controversial nature of what is considered transphobic and why there is so much disagreement. By the way, many would consider your above post highly transphobic and I don't just mean extremists; on a website like The F-Word chances are you would get flamed (actually your post probably wouldn't make it through moderation).
I don't think what you say above is transphobic, but I do think it is incoherent. Either one accepts transgender ideology, or one does not. Surely one cannot pick the bits that one is OK with but not others? Surely one cannot accept transgender ideology in some contexts but not in others? Surely that is transphobic?
Let me explain. Transgenderism (which is different to transsexualism) is based on the idea of a defining inner gender identity. If you accept that, (and it is transphobic not to) then the statement 'women menstruate' is always transphobic, no matter what the context. Because transwomen are women in exactly the same way that bio women are women but they don't menstruate - and to generalize about women in a way that dismisses or leaves out or erases women who happen to be transwomen, is transphobic. In other words, either you accept that transwomen are women and transmen are men - or you don't. You can't accept it some of the time and in some contexts, but not in others. That is transphobic. And incoherent.
On sites like The F-Word their guidelines about transphobia clearly state that any comments which suggest that transwomen are not real women or that they are somehow 'lesser' women or not as womanly as bio women will be deleted for transphobia. Therefore discussions generalizing about women with the assumption that things like menstruation, abortion, cervical cancer, FGM, pregnancy, hormonal contraception, etc, etc are women's issues or that they affect women in general, are transphobic (and essentialist). Because they marginalize transwomen and suggest that they are not real women. Which is perfectly logical and coherent IMO if one is starting out from the position of accepting the concept of inner gender identity and its role in how a person identifies.
What I see a lot of people doing is accepting part of the ideology but not taking it to its logical conclusion (in other words they accept the bits that fit in with their world view and politics but kind of ignore the rest). And that is transphobic and not a little hypocritical - especially if one is accusing others of transphobia.
Really if MNHQ want to draw up guidelines about transphobia they would need them to be very clear that there is absolutely no difference between bio women and transwomen and that we are in the same sex category. Indeed MN would find itself in trouble because many of the sections of the website would be considered extremely unwelcoming and excluding of transwomen on a site that is aimed at women (all women, right, not just bio ones) - sections such as the pregnancy, childbirth, antenatal, postnatal depression, miscarriage, breast and bottle feeding, etc exclude transwomen and carry the highly transphobic implication that they are not real women. MN would probably be breaking its own guidelines.
