I am not sure how many more times it can be said in numerous different ways.
The drugs a transitioned male takes has not been tested for in the substance they produce. Including the sometimes ineffective and unreliable testosterone suppression and like other sex hormones, I would expect that testosterone enters the milk. What effect does this having on developing infants? Is it lasting?
A male lactating does not have the receptors and the interaction with the infant to adjust the milk as a female does. So, what is the point of breastfeeding a substance that seems to lack the nutritional value and may have significant as yet unknown effects. Formula and other options are available.
Cow milk is tested for human consumption. I doubt that a female cow will be passing the same chemicals into the milk as males. It can be easily tested and it is also pasteurized.
Using the experience of a female who is taking drugs for chemotherapy which has been tested for in the past for safety in breast milk is a false comparator because the milk of males has had little testing. And as the mother of the infant, your body can do all the adjustments the infant needs in the make up of the milk.
There is little point in applying labels to the arguments and discounting them because they don’t fit into a box some
people seem to need them to fit into to be credible.
Again, what is the benefit to the child to feed that child a substance derived from a male no matter whether that male is a transitioned male or a husband who means well? What is the benefit of the substance is not adaptive as it is when a mother feeds her infant, and has unknown nutritional value?
Exactly what is the value to the child?
