Contrary to popular misconception, critics of the transgender movement do not disagree that trans people have "rights" as a monolith. They're talking about whether trans people have specific rights including:
- not being misgendered
- tax-payer funded gender surgery/hormones
- (specifically children) to get surgery at all without their parents consent (or with)
I don't definitely disagree with all of the above, but it gives you a sense of the reasonable criticism people can have with the concept of "trans rights" as "allies" actually mean it (not as the basic human rights they claim to mean).
I do definitely disagree with the right to not be misgendered, as that goes against the right to free speech, which I value a lot.
Trans rights I definitely agree with:
- having surgery with their own money as an adult
- social transition (excluding the bit where they force other people to play along calling them by their preferred pronouns using laws such as the German self-identity law)
- freedom from violence from bigots
Human rights are not just a stand-in for "things I like". They actually mean something. Namely, government force applied to protect a property of a human being or group thereof (legal right), or a moral obligation on someone to do or not do something to/for someone (moral right).
A legal right to not be misgendered means that the government passes laws prohibiting misgendering trans people. Think about that.
