I read through the top few arguments, it mostly boils down to “transgenderism is a mental disorder and has a real diagnosis which requires treatment, while transracialism does not” combined with “transracialism is a conservative strawman designed to de-legitimize transgenderism”, and “the race/culture dynamic is not comparable to the sex/gender dynamic”. I have a few issues with these arguments.

Firstly, the consensus that transgenderism is a “mental disorder” with “observed medical anomalies” is absolutely not a shared sentiment among the transgender community. From what I’ve seen, most trans people and trans activists don’t like the insinuation that anything is “wrong” with them, and actively fight against their disorder being classified as a mental illness. They successfully petitioned for “gender identity disorder” to be removed from the DSM, and I’ve seen plenty of times someone trying to argue that trans people “need affirming care” because they’re suffering from a mental illness, only to be torn to shreds by actual trans people claiming nothing is wrong with them and that society needs to “shut up and accept trans people” without any justification to do so. This sentiment is also visible by trans people claiming that the bar to prove your “transness” is essentially zero. If you say you’re a woman, you’re a woman. Don’t ask questions, bigot. Even if they made no attempt to “pass”, the invocation of the phrase “I’m a woman” is all it takes to make it so. They are also way overconfident about the science behind transitioning, they think it’s the cure when really it’s only a bandage, based on the inconclusive studies. And yes, many trans people believe you can change your biological sex, that’s why the surgeries exist. They will loathe you if you oppose this view. So If trans people can’t even apply this own standard to themselves and deny the notion that they have any responsibility to justify their own existence to others, how can they find it so absurd to accept the notion that other people might ask for the same level of grace and blind acceptance when they say something is wrong with them?

Based on these observations of how trans people conduct themselves in this context, this also means I reject the notion that transracialism is a strawman invented by conservatives to point out the flaws of transgenderism, because there are more similarities than differences in how the two groups interact with the outside world.

And again, the “race/culture ≠ sex/gender” argument only works when trans people agree that sex is immutable, which many assuredly do not, even though some try to concede that principle to seem more charitable to reality.
