i cant tell if youre being sarcastic or autistic here, but if youre being autistic you just admitted to not understanding simple sarcasm
like you said, not being able to understand sarcasm is a hallmark of autism. I thought the in all seriousness would have given the fact that it was the former, no?
Phenotype is based on appearance, and appearance is affected by genetic expression, which is in turn affected by your environment. Dying your hair does not change which genes are expressed in your hair follicles (besides the genetic damage you may be doing by bleaching, but that's not what is being discussed here), while taking HRT or having surgery does change which genes are expressed in your cells. Women with CAIS are not female in the regular, reproductive sense of the word - they are phenotypically female. I specified this about 10 times.
Since breasts are primarily composed of fatty tissue, I feel it appropriate to compare double mastectomy to liposuction and bariatric surgery. When someone gets bariatric surgery, the fat is sucked out of their chest cavity and tissue is removed from the stomach to reduce its size. Does the surgery change their genetic predisposition to getting fat or the genetic code governing the size of the stomach no. What it does change, however, is the volume of the stomach. If someone who has gone through bariatric surgery has sex, their children will inherit the genes governing the stomach. Similarly, if someone who has had a double mastectomy has sex, their daughter will inherit the genes covering breast size. I will give you the fact that HRT forcibly modifies genes to an extent, but it is inadequate for entirely changing one's gender. Test won't make your boobs magically go away, and estrogen won't make your dick magically go away. FTMs will remain high test females, and MTFs will remain high estrogen males.
I'll give an example for you. In the 1990's, the female wrestler Chyna took so many steroids (including testosterone) that she grew a small beard which she had to shave every day to maintain appearances. Despite this, her natural breasts remained unchanged in size until a ring accident. I will point out the fact, however, that they did rupture at one point and she had to get implants in the early 2000's. intellectual honesty is important, after all.
On CAIS, it is phenotypically female, genetically male, right? Let's say that they are indeed identical to you, as previously stated. if taking estrogen and other medications is enough to make you phenotypically female, then AGP troons count as female. You and I both know that they don't.
