> If a surgery changes their chromosome then they change sex too.
Now you've completely changed your definition in the course of a few minutes, but you still don't want to change your beliefs. Funny how that works. Imagining what your new definition will be, what if you have any of these sex chromosome anomalies, as more than 2 out of every thousand humans do? What if you use gene therapy to change your chromosomes but don't alter your anatomy? https://en.wikipedia.org/wiki/Sex_chromosome_anomalies
> What if I tell you I don't care what sex you are or you think you are.
Then why are you making a big deal of trying to define it for others and supporting those trying to legislate who can believe what?
> If someone believes for example, they are Apache Helicopter, good for them.
Certainly. That's no skin off my back, just like people believing in magical invisible beings and praying to them doesn't affect anybody else. Both groups can believe what they like.
Legislating who gets to identify as what when it's not hurting anybody does make society worse, just like the people who believe in magical invisible beings legislating what everyone else can do based on the voices they hear in their heads also make society worse. That is a problem worth fighting against.
