Yes. That was the poster on that JKR thread that I remember saying it.
It certainly puts the previous years and years of conditioning people that using sex based language rather than preferred language into a completely different perspective. It also now grounds transgender identities, all 130+ of them, firmly as philosophical belief as a commonality that is now loosely supported by those with dysphoria.
So, why is it that posters still come onto threads using hyperbolic emotionally manipulative tactics such as shaming and name calling because others choose not to comply with someone else's philosophical belief?
What moral grounds do posters have to do that in the face of the new information that transgender identities do not mean that the person with that identity has gender dysphoria, but merely chooses how they want to be referred to and expects everyone to just comply with that? What other group of people does society allow to make demands for compliance as we have been seeing for years, based on philosophical belief?
It certainly shows this group in a very different light when considering such demanded accommodations. Language, single sex spaces, educational changes, sports and medical treatment doesn't cover all those accommodations by any means. It is just a sample.
I don't believe that many people have realised that there has been this change. And considering the emotional investment that people have now made to make accommodations, will those people continue to make those accommodations?
