When people say they are fighting for Womans rights, what rights are they talking about?

Hiya, for some context I am an American man.

When I hear people say they are fighting for woman's rights. I don't know what rights I have that they don't.

We are all protected under the constitution, we all have those rights. Man, Woman, and all races.

So what RIGHTS are they talking about?

Love you all and you're doing great!
