M&S are also forcing a situation that means their role will be addressing any harm after it's happened instead of trying to prevent it in the first place. Yet again women and girls are subjected to harm before anyone will do anything about it.
How about making sure it doesn't have the opportunity to happen at all?
I am also sick of the wharaboutery, NAMALT and women can harm too arguments. Women don't rape and kill other women. Women who have been the victims of male violence (shockingly high percentage of the population btw) matter less than the feelings of men who think they're women. I don't care if not all men are violent, enough of them are that we deserve safe spaces when we are at our most vulnerable.
No one has been able to answer what actually makes one a woman if it's not biology? Womanhood isn't a feeling or way of dressing so what are tw actually doing to live as women? The argument falls apart if you give it a mere moment of critical inquiry.
We can't self identify as another race, as disabled or as a different age than we are (recently proven in a court of law) so why is sex any different?
By all means, it should be acceptable in society for people to present however they like. Grow your hair, wear a dress and make up, call yourself Jessica, I don't care. But the reality never changes.
Also what do people who drank the koolaid believe twaw think about a biological male with a penis fooling a lesbian into a situation where they may have sex? TRAs have accused lesbians of transphobia when they don't want to sleep with said tw. Should these women be allowed to reject a tw based on their body?
Do you stand with women and believe that we shouldn't be made to feel bad about our autonomy over our own bodies.
Think about the consequences this has for all women. Our right to give, refuse and withdraw consent is being removed before our very eyes and worse than that, biological women are helping make it happen.
And to PPs crying "judgmental", read Jessica Yaniv's conversations with young women online. Then come back and honestly tell us if you'd be happy for your young daughter to be in a state of undress mere feet away from him?
If you can't be bothered, ask yourself if you'd be happy for a man to approach her and ask if she needs help inserting a tampon, or happy to see his surprise/disappointment about the lack of naked female bodies in the changing room? Would you be happy for her to be forced to touch his balls even if she didn't want to (then be sued for bring so hateful and literally violent)?? 
This is about more than the feelings of men.
If there weren't so many strong women on the FWR boards, I'd honestly despair at the state of this place.
