Yes, this might make it more difficult for that minority of males who demand to use female spaces. That's the whole point.
Reproductive rights?
Paid maternity leave?
Equal pay?
Equal civil rights?
Acknowledging domestic labor as vital to the economy and supporting it?
It seems to me that people who get hot and bothered about “protecting” women’s restrooms don’t actually care about women, they just don’t like queer people.
For your information, I support reproductive rights including the right to abortion and I believe that paid maternity leave that is generous both in amount paid and length of time before and after birth is much-needed policy. Equal pay for the same work and equal civil rights are of course essential, and domestic labour should be valued highly rather than taken for granted like so much contribution of women is.
I also support equal rights for same-sex couples, including the right to get married.
So maybe reconsider your assumptions? Thanks.
Let's say you believe that trans women are men. And you believe you need to protect cis women. The number of trans women is so vanishingly small, that you've spent a huge amount of energy to prevent the 0.5% case. Legislating always has an opportunity cost, putting forward a bill means not putting forward other bills.
Women suffer domestic violence and sexual violence. 33% of women in the US report experiencing domestic violence. Protect women from that!
Because there are so many ways women suffer in this country, it's very difficult to take on good faith that anyone is protecting them by legislating against trans women. You could choose to solve any problem that affects women orders of magnitude more, but those problems see orders of magnitude fewer bills, if any at all.
No, the data shows this isn't about protecting women, it's about hurting trans people.
Your argument works both ways.
