“You obviously don’t know any biology.” and “Reducing testosterone makes almost no difference.”

You made me laugh. Not because you’re funny, but that the Dunning-Kruger effect is so strong.

If you take a predifferentiated prenatal XY mouse, and keep it on a lifelong T-inhibitor and estrogen source, it will be a female mouse in every sense — development, sex organs, instincts, everything you might think matters.

Any point after that mouse development, the mouse will react in a biologically female manner, and remaining male aspects act only on biological inertia (this is why Tanswomen go sterile — the biological prcesses to produce sperm have stopped even if the parts are still there, but transwomen will gain the ability to breatfeed. And, hypothetically, in event of a uterine transplant, would be able to get pregnant as well.)

I would recommend learning basic biology before complaning about people’s lack thereof.
