I care because women as a sex class are fundamentally different to men and the language used recently erases these differences.
The reason women face sexism is due to us having the majority of the reproductive burden and to suggest men could claim to be a woman and face the same thing minimises it.
Finally, I worry for the long term effects that this ideology will have on children as no enough research has been done in this area.
I have spoken to some friends and family regarding these issues, particularly the effects on children. I follow many gender critical people/organisations/communities to stay up to date and educated on the topic.
When speaking to one family member about the topic, I barely scratched the surface before they started calling me a “TERF” and saying they were disappointed in me. I haven’t touched on the topic with my family since.
