I never said any of those things but virtually no cis-females have dark voices. I don't support transgender people being in the limelight or taking controversial positions or playing with XX's. That was the stupidest idea in history and it greatly damaged all trans people and put them at risk. Nobody was even paying attention until Bruce Jenner changed his name and then the ridiculous 6' 4" woman on the Penn swim team that resembled Kramer doing karate with children. I am libertarian but very little good comes from highlighting all of this disfunction. Nobody could even tell unless they previously knew them, who transsexual women were. They were all required to take feminizing HRT and to get surgery and there were major gate keepers. Maybe those gatekeepers had benefits as well as negatives but....
This doesn't mean that a person can't actually become a female using hormones. You don't get pregnant or menstruate but visually you are cis looking and you are able to have sex three different ways. That's pretty close without any surgery. People relate to you as they perceive you so stealth is essential.
