And you are wrong to think that.
Which you should now realise because so many women after your post told you no, they don't fit your uninformed stereotype. Actually, it's not even a stereotype because there's not even some truth in it, it's just a nasty little idea you came up with out of your own prejudices. Feminist women on board with botox for 23 year old indeed - it's laughable. Sympathic maybe, understanding why women make those choices in the world we are in of course, but thinking it's actually a good thing? Hell no.
So don't be disingenuous. This is a thread about phalloplasty on a board specifically set up to discuss the impact of genderism(1) on women. Obviously it's going to be about trans people.
That doesn't mean, as you so arrogantly assume, that's the only thing the women here care about.
I don't spend time here talking about other Feminist concerns because I don't believe they are under direct attack in the same way that the fundamental right of women to define themselves as female and have legal rights and a social and political voice for those of us that are female is. Yes there are always groups that want to put women back in our box, take away abortion, reduce the protections we have but right now, by and large, they don't have the political and establishment support that genderism does. If and when they do I'll be fighting that as well, but for now the best way to fight for women is to be out in the world living every day and supporting other women - not cheerleading everything women do, but practical support with the challenges women face. Mentoring, donating, volunteering time, sometimes just being a role model of not taking everyday sexism.
(1) Genderism being the belief that the difference between men and women is mental not physical, that female people do not exist as a meaningful legal and social group and do not deserve language, rights or identity separate from male and vice versa, and paradoxically that many trans people have an urgent need to be seen as the opposite sex and have the right to medically adjust their body in pursuit of that)
