Questioning self ID and having empathy for people with a medical diagnosis of gender dysphoria are not mutually exclusive.
If I'd been born male, diagnosed with gender dysphoria, and fully transitioned to the point where I considered myself female, I'd be horrified to see men like Philip Bunce. Turning up at Credit Suisse on his "Pippa" days, dressed like a stereotype of a woman, and expecting his colleagues to accept that he IS a woman on that day, but also IS a man on another.
There's a serious and adult argument to be had about including people in the former category in women's spaces. There's an equal argument to be had about questioning the call for inclusion, at the expense of existing safeguarding policies (amongst many other considerations) by the latter.
Unfortunately the latter group are far more vocal and often display misogynistic views. They're allowed to be angry, and so are women. Hence the poster.
It's much easier to shout abuse than to become educated about an issue. Some people of course don't want to be educated, because they might learn something that makes them question their knee-jerk reaction.
I'm not in the least bit threatened by a fully and medically transitioned dysphoric person, born a male now living as a female. I still think their birth certificate should state male, as that's a historical record. I am however threatened by the idea that a male police officer could perform an intimate body search on me on the days that he self ID's as a female. He (and people on here) have the right to be angry about that. And so do I.
