You are correct on this part, but not in the way you are implying.
My youngest kid (now 16) assumed at a young age that they were supposed to grow up to be a woman and marry a man. Around their tween years, they were extremely moody, depressed, and questioning whether they wanted to live because they were having feelings that were very different than this. They opened up to us and we responded with support and love. They have been much happier and positive since then because they are comfortable with and are able to be themselves.
NOT giving gender-affirming care is putting these kids' lives at risk.
