Here is some yellow paper.
We say it is yellow because that’s what color it is.
Simple enough, let’s move on.
Here is some white paper.
We say it is white because that’s what color it is.
Now, imagine some stuff happens to the white paper - something spills on it, it’s left in the sun in a hot car, whatever. It is acted upon by some force, and now it looks like this:
We can now describe the paper as yellowed. It was originally white, but something caused it to become yellow. Yellow has happened to it - it is yellowed.
Describing someone as “transgendered” does not make sense, because that person has not been transgendered by anything. Transgender did not happen to that person, they just are transgender.
Just like you wouldn’t describe a black person as “blackened” - they weren’t originally some other color until something came along and acted blackness upon them, they just are black - you shouldn’t describe a transgender person as “transgendered”.
I love how simple this is, since when you use grammar terms (adjective, adverb, etc) people don’t always get it.
Okay, here’s the thing. I’m trans. And if other trans people tell me that “transgender” is right and “transgendered” is wrong, I’m happy to go along with that. And when a cisgender person says “transgendered,” I’ll say, “You should leave off the -ed. People prefer to just be called transgender instead.”
But this argument that it’s a fundamental part of language doesn’t actually make sense to me. And here’s why:
My skin is pale. I’m pale-skinned.
My hair is dark. I’m dark-haired.
My eyes are brown. I’m brown-eyed.
My gender is trans. So…
Again, I don’t say “transgendered,” because “transgender” works just as well, and only one of them offends other trans people. And if you’re a cis person reading this, you better not use what I’m saying to argue that you were right to call a trans person “transgendered.” Just fucking call people what they ask to be called. It’s not hard.
But when people try to make a purely logical, language-based argument for “transgendered” being inherently offensive, it never makes sense to me. Because that “-ed” clearly serves more functions in the language than you’re giving it credit for.
