Great gleaping globs of glorp! I was bored and decided to read this weirdass manifesto. (Well, I skimmed a few bits because... holy shit) Whoever is responsible for this has some serious issues. Pretty sure this person is genuinely a trans woman who has really bad concepts about gender and sex that have manifested as a lot of very strange ideas and attitudes.
I mean, I guess if you dismiss the idea of innate gender identity but your life improves after transitioning, it makes sense that you'd suggest that most males ought to transition to female (that's in there, and I'm pretty sure made it into a previous FSTDT quote). Really though, it just demonstrates that this person has basically no self-awareness. Makes sense for someone who seems to be a former "incel" though I guess...
The worst bit was the part where the author gives advice on self-administered hormone therapy, like dosages and such. Holy shit, go see a fucking doctor. I really hope nobody is seriously taking medical advice from some random crazy trans lady's internet manifesto.
