“I would argue strongly that all appeals to biology are anti-feminist. We can’t challenge the view we are limited by our biology in one breath and use the biology argument against trans women in the next. “
Appeals to biology from a feminist perspective are not based in being ‘limited’ by our biology, they are based in difference. Sexual difference. A difference that is/has been routinely, typically, ignored in all realms of human endeavour. For example crash test dummies, pharmaceutical dosage, employment law etc. This is based in materialreality that can be evidenced and related to our particular female biology.
An anti feminist view of female biological limitation would be based more on the idea that menstruation makes a person unstable and unfit to be a pilot, that girls shouldn’t be educated, that girls should have their clitoris removed to avoid them becoming loose through sexual pleasure, or the idea that-the capacity to become pregnant makes a female naturally more nurturing than a male. These are views based on cultural mythology, rooted in ideas about gendered roles and applied to female biology by believers, evidence is not necessary.
The biological arguments around, not “against”, trans women are based in the same material reality as the first examples:
Crash test dummies were for decades based on male physique, weight distribution, height etc.so a trans woman’s body would more typically match a crash test dummy than a female (or a trans man’s) body so they would be safer in any vehicle using said crash test dummies.
Dosage of pharmaceuticals is typically based on the male biology, though it is adjusted according to height and weight there is evidence that female bodies absorb some drugs differently, in addition to this, no testing is carried out on pregnant women for reasons that might seem obviously ethical(to protect the foetus) but with the result that there is limited evidential basis for the medical treatment of pregnant women, who, amazingly, have a humanity of their own, separate from the foetus. Trans women, having male biology, are not affected by any of this. Trans men, having female biology, are.
Employment law was for a long time arranged around the idea that as soon as a woman was pregnant she should be fired. This obviously would not apply to trans women, but might apply to trans men.
Hopefully I’ve demonstrated that arguing about sexual difference is not the same as arguing about sexual limitations.
