I've encountered this weird extremist idea too. It's like... often it's Americans, who live in America, and think both Israel and America should be destroyed. But they don't want to do it themselves; they just want to feel like good people for calling for that. Because the rest of the time, they just feel bad about living on stolen land.
The specific call for destroying-Israel-and-America is a huge red flag for propaganda from the dictatorship of Iran. Like, I promise you there are not two (2) lone deeply evil countries on earth that should be nuked from orbit.
But there's definitely one (1) deeply evil dictatorship on earth that specifically and routinely calls for that.
There are many (many) countries on earth with extremely complicated histories full of ethnic cleansing, slavery, and genocide.
(Many of them way more recent than the U.S.'s practices of ethnic cleansing, slavery, and genocide. Myanmar just ethnically cleansed the Rohingya Muslims a few years ago, and nobody would suggest we should wipe Myanmar off the planet.)
Sometime in late 2023, I was beefing my way through some instagram comments, and a nonbinary Ethnic Studies professor genuinely told me that someday, trans women of color would do to the U.S. what Hamas had done to Israel.
I honestly don't know what leads someone to go, "aha! this is the one specific demographic that actually deserves to be here, and to torture, mutilate, and burn its way across the country in order to claim it." (And the demographic isn't even "people indigenous to this land.")
I do assume this person was unaware of exactly how fucking brutal Hamas's attack was.
But the idea that trans women of color, as a group, are like, "Wow, I really wish we could slaughter and conquer America, including cis indigenous people, transmascs, an unknown number of enbies, cis people with disabilities, cis Black people, white trans women," and so on, is just fucking mind-blowing to me.
Like, I absolutely understand that we all feel this level of rage at our oppressors sometimes. But most of us recognize that it only works as an angry fantasy, and in real life would be like trying to rebuild from an apocalypse.
I don't even think this person counted themself among trans women of color. I think they were just making a really impassioned statement without thinking any of it through.
I also don't remember who it was that said, somewhere in the weeds of tumblr discourse, that we should destroy Japan too. They wanted to destroy Israel because they thought it was an ethnostate. The response was that there are many countries whose populations are basically one ethnic group, like Japan (which is not what an ethnostate is, but it's what most people seem to THINK it is); and they immediately and enthusiastically included Japan on the list, to the absolute bafflement of everyone else.
I think there are a lot of people who are very scared and angry, and don't really care about anybody or anything; they just want to lash out and imagine their problems could be solved through violence.
And also, a non-zero number of those people have unknowingly absorbed the concept of scapegoating Jews.
