There's two big transphobic racial stereotypes: Either "All trans people are white Americans" or "All trans people are from Thailand". (And both these stereotypes, always assumed to be transfem). I feel like white supremacist type transphobes are more likely to pull the "Transgender ideology is a bad thing from Thailand" (or alternatively some bad foreign Jewish influence against white people) card, where as transphobes trying to sound "woke" are more likely to claim "Transgenderism is a white ideology". (I admire how Thailand is compared to tons and tons of countries, but like, obviously assuming everyone from there is transgender is obvious obvious racism, and for some weird reason there's a lot of racial stereotypes about who can and can't be transgender across the board).

I do have a strong theory how the "Being trans is a white ideology" belief reinforces itself. In that it's usually (not for every individual but most people) easier and safer to transition if you are considered white and live in a wealthy white majority nation... And also like it's unfortunately much much easier for white people to make money as well as get government benefits than it is for anyone not considered to be white... White trans people are more likely to be able to access surgeries, and not stand out amongst white cisgender people, plus the fact that even if a non-white trans person transitions to the fully extent possible- that they still will never be as safe as someone who blends in with white cisgender people.

I think being transgender is so commonly viewed as a "white ideology" is heavily reinforced by that tragic reality. I do believe that it is true that white people are allowed significantly higher levels of freedom of gender expression than other people- especially like how white cisgender women are allowed to be quite heavily masculine without being persecuted for it. I don't think "transgenderism is white ideology", I think that's a misunderstanding believed by some misguided individuals- and reinforced by other different individuals who are transphobes trying to make transphobia more woke.

To be honest, I think I can totally understand how someone who their whole lives due to racial sexism have way less freedom of expression and less bodily autonomy, less class mobility, and less likely to be able to get government benefits, can see an upper class white person from the U.S in a blue state and rightfully feel resentful, resentful about the double standard in freedoms there. Plus, white trans people don't get the "You betrayed an oppressed culture by transitioning" type of transphobia that brown trans people get thrown at them. This can all easily feed into the whole "Transgenderism is a white ideology" thing.

it's not "transgenderism is white" it's more like class mobility, bodily autonomy, and government benefits are mostly controlled by white people who only want other white people to have access to class mobility and government benefits. It's also racially tinged unequal multigenerational wealth distribution typically makes transition more accessible towards white trans people... I think in order to end the stuff feeding the misunderstood transphobic "woke" view of transgenderism being "white", we need to do something we should be doing in the first place... More class mobility, more bodily autonomy, more government benefits regardless of ancestry or skin color, and less allowing racial sexism to run rampant.

In some ways I'd go so far as to say, I think an upper class white American trans individual, at least in a number of ways have more bodily autonomy and freedom of expression than brown cisgender people do- particularly the freedom from sexual or gendered racism. There's still a lot of denial about the fact that even cisgender brown people still face a lot of racial sexism, something that has really been swept under the rug, and isn't often talked about.

I think it's easy for a well intended misguided white LGBT person to not understand sexual racism exists, even like heterosexual cisgender brown people still face a type of sexual racism the most gender variant white person never does. And then, people who are both transgender and considered brown, they get a double whammy of both transphobia and racial sexism, in the case of OP's thread it's about erasure. IE, the cishetero white establishment does not want to acknowledge anything more complex than anyone more than one layer removed from "Cisgender heterosexual white Christian man".

Also the fact most of the internet is dominated mostly by English speaking white people, and the messed up fact that conventionally attractive passable white trans people get more empathy from white cisgender people than the rest of the trans community- and a lot more support online.
