Feminists advocate for the rights of women but not exclusively so. We advocate equality and address inequalities. Feminists support men as well when they are victims of inequalities. Of course, feminism is a broad movement and not a dogmatic cult, and therefore you will find those who do not support the rights of trans people, but they are not representative of the majority of feminists.
Since its inception in the 19th century, feminism has expanded to address all aspects of gender in culture and identity. Many feminists like myself do not consider gender to be a binary position but a spectrum of cultural expressions. It is therefore impossible to advocate the rights of women without advocating the rights of men because no one is entirely "man" or "woman." No one fits neatly into static gender stereotypes. The rights of trans, intersexed, and genderqueer people are extremely important as we move forward.
In the long term, I feel it's especially important that we question traditional gender roles because we have an increasingly powerful ability to manipulate our biology. We will see increasing amounts of people with bodies and minds that do not conform to our expectations because they are fundamentally different, and we need to develop a cultural understanding for relating to people who do not conform to our preconceived notions of gender expression.
> If you believe that modern western cultures are not gender biased and this state of affairs is worth preserving, then you are a feminist! You can't deny it because you have just advocated for gender equality.
No, if you're going to insist on naming it, it is "egalitarian". I also don't believe this state of affairs is worth preserving.
>Feminism advocates for autonomy for everyone.
No, no it doesn't. Feminism, by design and definition, advocates for the rights of women. Or rather, I should say, "womyn" since large, vocal factions of the feminist movement don't support the rights of trans-people. But I'm guessing you're one of those feminists that like to no true scotsman those feminists out of play, I guess their opinion don't count.
Also, fuck your patriarchy bullshit. It's a convenient scapegoat and surrogate evil upon which much of modern feminist dogma is based.
