Possibly a helpful idea to straighten things out in mind is to stop thinking of specific social groups and the implied special rules and just think in terms of:
I don't agree with anyone experiencing reduced access to law, justice, public spaces, employment and employment law, education, health care, conditions etc for any reason pertaining to their race, religion, sex, sexuality, gender identity, disability, political affiliation.
I don't agree with anyone experiencing harassment, intimidation, assault or violence for any reason for the list above.
This includes women. The law supports the above. Equality.
Not special permissions for special people, who are only happy if another group is suppressed and oppressed by being denied equal access to the above to prove how very much more special the special people are.
I can believe in the laws protecting from discrimination above and still believe that TW and women are two definitely distinct groups, need different things, and providing for in different ways. And that someone's personal choice of gender identity can be respected without their requiring the erasure of the female class, their rights and provisions. And that sane people have no problem understanding this.
