Treatment for gender dysphoria aims to help people live the way they want to, in their preferred gender identity or as non-binary.
Some young trans, intersex, and gender non-binary people may decide to take puberty blockers after talking about it with their parents or guardian and a nurse or doctor.
Look, you have a lot of reading to do. Or better yet, talk to a trans person. In real life. Ask them about their experience. Ask them what that feel, how they want to be called. Ask them what’s up.
You have these strong opinions. Have they come from the people who are the subject of these opinions? This is your fellow man, always has been. Right now we are in a time where trans people can be “out”, and can talk to you openly about being trans. Don’t waste the opportunity because it might not last long.
Maybe you’re right in everything you say, but to be sure you need to talk to some real trans people face to face. There are plenty of them about. Go and do it.
