Biology is very complicated, but humans are either male or female. There are only two sexes. It's not possible to be born in the wrong body, we all get the body we are in, like it or not.
That some people have disorders of sexual development or gender dysphoria doesn't mean that there's anything other than two sexes.
There is absolutely no way, as we can see from the video posted, that sex can be described as a spectrum unless you use people with DSDs as your basis. People with these differences keep asking transpeople to stop using their bodies as explanations to fit the current narrative some activists are aggressively supporting - that sex is a spectrum.
They keep also bringing the phrase 'high school level biology' to shut down any disagreement.... ah. no.. I get my knowledge from published articles by Dr's of developmental and evolutionary biology who disagree that people with these rare differences explain a spectrum. They are male or female still. Each sex has its own spectrum of body differences, but sex is binary.
So, apart from this video link, is there any evidence to support what seems to be a pseudoscience theory that sex is on a spectrum? One that doesn't appropriate people with DSDs bodies? Or even hint at people with DSDs bodies?
I would love to add it to my reading list which is wide and varied.
