There are many of us who have experienced this.
The issue comes from the expectation that everyone else then has to use the language you feel comfortable with.
If all someone did was choose to undergo extreme body modification, and announce that they had terminology to refer to them that was completely new and not referencing anything else that changed the definition of that other thing and that was all, great. Others do that now with other identities.
There should never be laws upholding a personal demand to be treated as if your personal reality that is not material reality is everyone else’s material reality. If you wanted to label yourself as something, you should be free to do that. But society should not have to treat that as being materially real if it is not.
If a group of male people all cosmetically changed their appear and adopted a new label for themselves that was absolutely unique to them, but didn’t demand that they were not male people when sex matters, and didn’t demand that society change the language away from sex based to suit them, maybe we’d be in a different position.
No one should get to dictate common use language be changed to suit them specifically. There has been this false expectation set that this is the case. It isn’t.
However, a group of male people who have changed their appearance to fit an identity but still understand they are male, who understand that they are rejecting the single sex provisions for their sex but campaign for additional provisions open to all people that suit their needs but never expected to be treated as female when they were not, who understand that some people will still choose language based on sex but it is not hatred for them to do so, surely that was a basis to work on.
That didn’t happen though.
Instead, a group of people leveraged the philosophical theory that what they said they were, they were. Even if these claims had no basis in material reality. They also then have tried to force compliance either through emotional coercion or coercive policies that people act as if they believe something that is not materially real. Why should a group of people in a democratic society have the right to do this?
In other words. If someone wishes to change their bodies and declare they are now a [insert created term here], ok. They should not be discriminated against in finding a job that isn’t for a protected characteristic, or in accommodation or health services etc. If they don’t want to use single sex provisions for their sex, they find alternative / campaign for solutions that are not for the opposite sex that they are materially not. They should not get to enforce language change. And if they want additional provisions for themselves, then they have the same rights as everyone else to campaign to get those.
