It’s too much to engage in a full on biology lesson, but my point stands saying if you are biologically born a male you will die a biological male is too broad and open to argument. No, that point doesn't stand, you haven't provided any argument for it being "too broad" either.
There is lots of variation in biology, so what if a MtF voice, breasts, vagina, vulva, labia, uterus, voice etc are all feminised by surgery. Exactly, it's just a variation in men. A post surgical man is still a man.
So what if it’s hormone or laser surgery removing the body and facial hair.
Exactly, this is just aesthetics.
So what if puberty blockers result in female levels of muscle and bone density.
These drugs result in physical damage, there's no "so what" here I'm afraid.
The fact is it’s still biologically permanently done to a male body yep
such that it is no longer biologically male. Says who?
The human in question doesn’t have to be exactly, biologically a female, to not be biologically male at death. This doesn't mean anything. Everyone is either male or female.
Even today, the majority of the visible and many of the internal biological markers of a woman are in fact present by death if you are MtF
No. This is not true.
so I don’t think that one can safely say if you’re born a male you biologically stay male until you die. Too much can be done. So much of your external and internal biology can in fact be altered, be feminised.
You absolutely can "safely say" that a male remains a male, as there is no way to make him female. Feminised aesthetically, not female.
You don't half chat a load of shit.
