I feel bad for the 15 year old truscum desperately trying to argue that gender isn't a social construct and other such blatant bullshit because they're clearly miserable and self-hating, but I will never feel bad enough to not block and report them for hate speech.
It's not "internalized" transphobia anymore if you're targeting others. At that point you are just a transphobe, and you are just as bad as cis transphobes, and in most cases, actually worse, because you're in the same boat, but you're still doing everything you can to sink it and throw people overboard.
To all the truscum reading this post: gender is a social construct. Arguing that its not just makes you racist and transphobic and it makes you look ridiculous because it means you clearly don't even understand the words you're using.
Gender is a social construct. Gender is not some biological fact hardwired into humans in particular and people in general. The white (and especially white Christian) concept of "man" and "woman" and the roles assigned to such are not hardwired into the biology of the species.
Gender is not inherent to the species, world, or universe. It is something created by the culture it exists in, and when fucking white people invaded and colonized most places on the planet, they brought their genders with them and did their best to destroy the ones that were already there.
Gender, like money, is a social construct. It has only as much value as we assign it.
This doesn't mean money isn't real -- you can't just tell your landlord, "sorry, money's a social construct, so I don't have to pay rent".
And it doesn't mean gender isn't real either. But it does fucking mean that the white concept of binary genders is not universal or inherent or the "most real" or any bullshit like that.
Like I'm sorry to break it to you, but no, you do not have a "male brain" in a female body or a "female brain" in a male body. That is not how brains work. That is pseudoscience used to justify misogyny. Using the argument that women should be oppressed because they're just biologically weaker/less capable/intelligent is not the fucking hill you want to die on, and that is what you are doing when you're trying to make the argument that physical brains are gendered and that's why you're trans.
Arguing that the white concept of binary genders is inherent to the universe and the only real gender is literally just racism and transphobia. And furthermore, you are very blatantly just trying to reframe the "there are only two sexes" argument but trying to make it your specific flavor of trans friendly, except it doesn't fucking work because that's never been how people have ever fucking worked.
Trying to forcibly shove almost eight billion people, not even including all the countless people who have ever lived, into two tiny boxes with no variation or anyone going outside the boxes will never fucking work. Stop trying.
Gender is a social construct. This does not mean gender isn't real and doesn't impact people. Money is a social construct, but you still need to pay the rent and use it to buy things.
Gender being a social construct does not mean you're not actually a man or a woman, regardless of what gender you were assigned when you were born.
Being trans does not make you the authority on gender. Being trans does not make you an expert on gender. Being trans does not excuse your racism and transphobia and willful ignorance.
Genders outside the binary of man and woman exist. To argue otherwise is racist and transphobic, and you are no less transphobic for being trans. It actually, in fact, makes you even worse than cis transphobes, because you are attacking the people who would be happy to stand with you if you'd just stop being a fucking bigoted asshole for five minutes.
