Puberty blockers are used for other medical issues and aren't considered dangerous or life damaging. Anyway this topic is somewhat meaningful to me because I really don't think people know how truly valuable it can be for someone to stall puberty when they desire to.
I find it appalling that cis society is quick to make sure no confused cis kid is harmed while ignoring trans kids that end up permanently disfigured by their voice & appearance from the wrong puberty. It's basically comparable to a cis kid having the wrong hormones damaging their body through puberty like a boy growing breasts and people just shrug their shoulders when it's a trans kid.
For context I went through the wrong puberty (I'm only 30 years old) and recently have been diagnosed with cancer. I'm choosing not to get treatment for the cancer and so I can get Medical Assistance in Dying because Gender Dysphoria sucks while all surgeries to possibly fix voice or appearance is like putting a downpayment for a house. Also was disowned by parents and struggled through university years because of constant bullying. Anyway I really hope people can take the time to consider that some kids truly know they're trans and it's not a fad to them.
