Women's rights are undermined by anti-trans activism. It promotes gender conformity, disparages female accomplishment in sport, and encourages the idea of limiting what young women should be able to do with their bodies
That's absolute nonsense. GC women embrace gender non-conformity; many of us are gender non-conforming ourselves. Wear what you like, just don't mistake your clothing choices for being a member of the opposite sex.
Disparages women's sport? The fact that makes puberty means men are faster, stronger and punch harder doesn't mean women's sport is less valid.
Usain Bolt can't outrun a racehorse, that doesn't mean he's not incredibly fast.
Protecting the female sports categories from men with trans identities or DSDs is recognising and valuing the achievements of female athletes. Otherwise you get the travesty of three male athletes on a podium in Rio claiming medals that belong to women.
If by 'limiting what young women should be able to do with their bodies' you are referring to cross sex hormones, binders and mastectomies - YES. I will give that one, we do want to prevent young women from making irreversible alterations to healthy bodies that are dangerous, damaging and can shorten their lives, put them at risk of heart attacks and strokes, experience menopause in their 20s, vaginal atrophy, loss of fertility, etc etc.
We are also against gastric bypasses for anorexia.
If you aren't against these, you might want to have a good long think.
