No one says trans people are not human!
That's just a scare story Genderist ideologues tell trans id-ing or aligning kids and young people to maintain their control of them.
All anyone is saying is that gender identity is not sex - I mean, that's the whole basis of trans identity, right? - so having a trans gender identity does not make you the opposite sex.
All the mess, all the lawsuits, all the protests, all the fear, all the anger, it just all boils down to that simple truth - TRAs are demanding something unreasonable, that because of the gender of their personality, we should for some reason have to pretend they are a different sex in the body, and pretend that the actual sex of their body does not matter.
But it does matter. Pretending it has gone away does not make it go away. And exactly because trans people are just normal humans, their sex matters just as much, or just as little, as everyone else's. There is no one rule for trans people and one rule for everyone else here, there is just the reality of the times sex matters and the time it doesn't.
Eventually, you got to allow the possibility of being wrong about it, even if it may feel like an earth-shattering idea. But once you do, you may get the answer you seek, especially if you actually meet some gender critical people and learn that despite what hate group campaigners tell you, those are actual humans, despite you refusing them basic dignity.
