But it doesn't affect benefits, access to housing, pension,...signing contracts, being allowed to drive, marry...
I thought before the pension age became equal, men legally identifying as women got their pension earlier?
Likewise marriage. Same-sex marriage wasn't allowed. Which is why identifying as the opposite sex suddenly made it possible.
The marriage contract is under threat. A spouse is going to have the terms of their contract change, if they are suddenly in a homosexual marriage, without their consent.
If a man Identifies as a woman, then suddenly all women's rights are ceded to him. Undeservedly.
It's exactly the same as identifying as another age. The only difference is possibly in the number of ways in which it can be exploited. The mechanism is identical.
