Yes, you absolutely can. I'm not dismissing gender dysphoria. There are many remedies for gender dysphoria, chief among them at the moment being transition. I'm not opposing that at all.

Give trans people safe, effective healthcare, challenge stereotypes that control how people are able to present and behave, combat the workplace and other forms of discrimination that affect trans people. All of these are genuine attempts to help people with dysphoria and I support them fully.

But it's insane to suggest that matters of material physical safety shouldn't take precedence over possibly not 100% validating somebody's feelings. Women in society, for a number of reasons, need us to understand the difference between somebody's gender identity and their biological sex. It is the same way in cultures throughout history and from all over the world. Including cultures that were centuries quicker in recognising and accepting gender "non-conformity." As I mention in the article, these cultures don't claim that those identities are identical to women and men.

If the price of maintaining spaces that offer women physical safety and sporting opportunity, is that the very small percentage of males who simply say "I'm a woman and want access to all female-only spaces," aren't 100% validated in every conceivable way, I think that's a fair price to pay.
