It is fucking hilarious that these mentally-ill, delusional degenerates think this way. Like did they seriously think that by taking some hormones, that they would become Gigachads? The woman in the OP reddit post DESERVES to be balding for her delusions and idiocy.
Changing your name, voice, clothing, and mannerisms might make the feel like they can LARP as a man, but nothing can truly change their biological nature. Genetics, chromosomes, DNA, etc, determines much of a person's life, whether they want it to or not.
Taking male hormones, especially post-puberty, is simply only going to give these trannies some of the negative effects of being a man, such as balding. Hormones in post puberty cannot change your height or bone structure, and nothing can actually change your gentials, even the horrible surgeries they get to create those disgusting, rotting, pus-filled, hot dog-looking, skin penises. And women will hate to admit it, but most of them will look like subhuman manlets when they transition to male. Just as many men look like ogres in drag when they transition to female.
