Yes, bodies can be flawed. We determine they are flawed based off normal, healthy, fully functioning bodies. Eyesight that is 20-60 is flawed because normal good eyesight is 20-20. A body with 6 fingers on one hand is flawed because normal healthy bodies have five fingers per hand. Someone who suffers from multiple sclerosis has a flawed body because they have a genetic code that has deviated from how it should all be, how normal people’s genome is sequenced.
A man or woman suffering from gender disphoria does have a flaw. It’s a mental flaw and they suffer from a form of mental illness. The body, except for purposes unrelated to their disphoria, is not flawed . It is functioning exactly how it should be. It has all the parts it is supposed to have. It is a perfectly healthy human body. It is either male are female. This makes them male or female. It is coded into the very DNA. If there is a incongruence between the body and the mind, it is the mind that has the flaw. It is physically and metaphysically impossible on this earth that an individual has a wrong body.
Their body makes them male or female. To claim otherwise is to invent a whole stream of pseudoscience to support an ideological position that sex is fluid. You might equally claim that a woman who believes she is a cat really is a cat. Or a man who believes he is a baby really is a baby. It is nonsense.
Lastly I apologize for the repeated incomplete posts. I am posting from my phone and it keeps going haywire and selecting 8 different buttons at once on its own.
