[deleted] I am not sure I can agree with that assumption. Though I personally haven't found a community of Transgender that share any of my values, interests, or goals in life, it seems obvious there are a wide range of very different Trans Cultures in just the United States of America, alone.
When we take into account all the other nations and diverse cultural traditions, that adds significantly more to the spectrum Trans expressions of identity. Now I do acknowledge that because of the Internet we see more and more common ideas spread and adopted,but I don't see that as the same thing as a mono-culture or erasure of diversity.
The only exception to this is the worldwide export of White identity, almost a commercial brand. I am 62 and throughout my childhood had many pen pals around the world in a time before the Internet. At that time people of European descent thought of race as Irish, Welsh, Scot, French, Danish, German et cetera. Any mention of White as a race was always presumed to mean Americans. That has changed dramatically, and so now we can see hundreds of YouTube videos of Europeans of every nation self identifying as White in what was once, an exclusively American fashion. I think in no coincidence that the rise of this self-perception runs in parallel with the rise of a reactionary White identity and a rebirth of Fascism is many of these same countries.
In every case, can be found the support of American White Nationalists of one kind or another. The era of Trump didn't just happen overnight, but has been growing here and abroad for some time.
