If they did, switching from testosterone to estrogen would change a person's entire personality or set of interests instead of just making it a little easier for them to cry.
Untrue. Neural pathway development that has taken place under one set of conditions is not instantly overwritten by changing the conditions.
As for the rest, TG are possibly a valuable dataset but not an especially easy one to study as they've already shown one significant and poorly understood aberration from the norm. Also, I find it difficult to take you seriously if you find simple gender nomenclature offensive; it does not speak well of your ability to accept what is over what you wish to be.
Which would be a valid point were it not a strawman argument. Significant != primary. There likely isn't even a primary cause with as many factors as there are to take into consideration.
It is extremely difficult to isolate a variable in living human beings' behavior yet you want to completely discount actual physical and chemical difference in the one organ that controls all decision making. That is willful blindness at best and at worst outright politically motivated fraud.
Gold is not succeptible to a typo sending it into a black hole. Gold doesn't require multiple backups to avoid losing everything to a drive crash. Gold is exceedingly resistant to hacking. Gold transfers do not require you to wait for 2-10 verifications. And last but certainly not least gold has intrinsic value since it has uses other than currency.
BTC has its potential uses but as a currency will never be one of them if only because of the extreme slowness of verifiying a transfer compared to say a credit/debit card transfer.
