Let me explain my view on Genderfluidity. Before you make any assumptions about what I'm saying here, make sure you read the full post, cause the point isn't clear until the end.

First, I think when it comes to facts about sexuality there are two primary categories to look at. Genderfluid doesn't really fit into either of these and rather instead fits into a third one that I think as a society we need to move away from to truly move towards tolerance.

The first category is physical sexuality. This is what a lot of people generally mistake Gender for meaning. This is the case of what genitals do you have? A male has a penis, a female a vagina. Someone who began as a genetic male and has taken steps to change that can be transgender. There's also the less common ones, such as that village where some children change sex at 12, or other uncommon genetic effects on sexuality. Genderfluid as I understand it is making no statement about this category. You can be genderfluid as a male, as a female, as transgender, anyone can be Genderfluid.

The next category is orientation. This meaning what are you attracted to. Opposite sex, same sex, both, nothing, ect. As far as I know, Genderfluid isn't really stating anything about this either. You can be heterosexual (as in only liking the opposite sex) and identify as genderfluid, because you identify with the traits of other gender identities. You can be any orientation and be Genderfluid. So, this category isn't relevant either.

So, what is it relevant to? Gender identities. My understanding that Genderfluid is essentially a way of saying what gender identities and norms do you associate with and that you don't necessarily conform to any one identity. To break this down further, it's essentially the personality of the person. The previous categories don't matter, it simply what your personality is in direct relation to societal norms on gender. An example of another similar identity is metrosexual (though this one is tied to a specific category), which is basically saying you don't conform to male stereotypes.

My issue with this though is that creating separate gender identities is merely reinforcing society's gender norms. By saying you don't conform to any one gender identity, you're acknowledging the existence of all those. The same norms that tell people who identify as male that their personality should include all those "manly" traits, or people who identify as female that their personality should include all those "feminine" traits. Even further, these norms have begun to be applied to LGBT communities, to where people expect them to act "gay", expecting flamboyancy. I think that drawing these lines is harmful, and the claim of being Genderfluid is just drawing another line.

Instead, we should seek to separate society's connection between Gender/Sex/Orientation, and Personality. Rather than tell people that you identify as Genderfluid, just be who the fuck you want to be, and don't feel like you have to explain it or answer to anyone about it. Be whatever gender/sex/orientation you are, and act however you want irregardless of the former. Then we can finally begin to see the decoupling of gender and these norms. Then people will begin to be more tolerant, because everyone's personality is unique rather than being sectioned off into stereotypes and identities.

That's just my opinion though. Feel free to rebuttal, but I just think the whole thing is counter-intuitive to what the movement about sexuality has been trying to accomplish.

EDIT Tl;dr : We don't need a category to define people who are unique and don't conform to gender roles. Instead, just be who you are, and we can eventually break down gender roles.
