Trans feminism sometimes gets mistaken as feminism’s little cousin, a mere side show to the Main Event: Cis Feminism i.e. feminism written by and for other cis women.
On a superficial level, this seems fitting. After all 99% of women on this planet are cis so it makes sense that “feminism” is largely concerned with the perspective of cis women. According to this logic, “trans feminism” is merely “feminism light”, a pale shadow of the real thing.
But I want to argue that not only is trans feminism real feminism, real feminism *must* incorporate the insights of trans feminism if it is to be complete, to the extent any feminism can ever be complete.
Intersectional feminism is basically the idea that if you are a black woman the oppression you face as a black woman intersects with the oppression you face as a black woman. Gender and race also intersect with socio-economic status, disability, orientation, etc.
Being trans is just another axis along which intersectionality functions. Any feminism worth its weight recognizes this. Trans women have experiences that overlap with cis women as well as experiences that don’t. But that’s not inherently different than black women having experiences that overlap/don’t overlap with white women.
In my opinion it’s a fool game to try and find the experience or set of experiences that is universal among all women. But that doesn’t entail the concept “woman” is without meaning. Philosophers have noted it’s surprisingly difficult to give necessary and sufficient conditions for simple concepts like “chair” – yet I know a chair when I see one.
Why should we expect complex concepts like “woman” are any different? I might not be able to define womanhood precisely in such a way that will correctly sort billions of unique individuals into two mutually exclusive classes: women and not-women. It’s not so easy! Yet I know a woman when I see one. And “seeing” here is of course a metaphor for understanding. A pre-transition trans woman can radiate her womanhood without necessarily “passing” as a woman. “Passing” as a cis woman is such an arbitrary standard anyway because there are cis women who get misgendered on a regular basis.
Why will feminism never be complete without the inclusion of trans people? Because feminism has inputs. It’s not just done completely a priori. It operates with experiences and narratives as data to be explained. Traditional feminism started with only the experiences of white middle-class women as the inputs and got quite a bit done. But it was far from complete. Then black feminists started feeding in their inputs. And through similar processes the voices of people from diverse backgrounds have given their inputs.
Trans people represent 1% of the population. That might not sounds like a lot but that’s millions and millions of data points. And furthermore, they are data points that are highly relevant to feminism insofar as trans people have unique insights into the dynamics of gender, which should be of special interest to feminist theory. So not only does trans feminism bring the experience of millions of trans women, trans men, and non-binary folks, it brings it in such a way that has the potential to reshape the very concepts central to feminism.
Some prominent feminist theorists such as Judith Butler have recognized this conceptual potential and have started to work through those insights. And of course trans feminists themselves have been dissecting this stuff for decades.

But feminism has yet to fully digest the trans experience. Though a mere “1%” trans folks have so much to bring to feminism, with spectacular proclivity to keep pressuring feminism to remain intersectional.
A common phenomenon in intersectional feminism is a feminism that believes itself to be fully intersectional yet is missing the perspective of important class(es) of people. To me it seems the best tactic is to remain humble about the intersectional reach of our feminism. There are probably voices feminism has yet to hear, stories that are important for understanding the full operation of intersectional semiotics.
Any feminism without trans experience is partially blind. This is why trans feminism is real feminism. Real feminism is spongelike in its absorption of different perspectives. Any feminism that fails to uptake the experience of trans people is incomplete at best and actively harmful at worst.
