Before starting, I want to emphasize death to 
and that this rant does not pertain to genuine European leftist comrades.
Especially on r/shitamericanssay back on 
(I know there are some very based comrades that participate in the sub), I see a bunch of Europeans shitting on Amerikkka for being the cancerous hellhole that it is. As much as I approve of shitting on this pathetic excuse of a nation, I just can't get across the fact that the vast majority of individuals like that are nothing but a bunch of chauvinistic hypocrites with a chronic superiority complex and an insatiable hate boner that which they conceal by LARPing as leftists.
Thing is, almost every single anti-American 
I meet online range from nothing but a glorified bunch of succdem chauvinists that stroke their hate boners (and PRETEND to "begrudgingly" kiss China's ass) to get off to the fact that they are 10% less shitty than the worst cancer to ever plague mankind at best, to straight up neolibs advocating for Russian genocide shitting on their big daddy Amerikkka for not funding the Ukraine war enough, or to God forbid, the typical Euronazi idiot making fun of the "racially impure Mutts".
Speaking as an American leftist, I know that non-American comrades are fully able to discern me from the idiots of this shithole, respecting me as another fellow comrade. But on the other hand, those hateful, bitter Euro nationalists aforementioned would most likely treat me as a subhuman cancer cell just solely based on the fact that I'm a Yank.
At least, in my personal experience, Y*nkkkoids online don't sugarcoat their shittiness (as they do in real life). They're some of the shittiest people you'll ever meet but at least they're consistent with their shittiness, flaunting their hateful idiocy and fervent anti-communism for the whole world to see. Eurolibshits, on the other hand, pretend to be morally and intellectually superior and enlightened when in reality, they're nothing but another group of bitter, hateful bootlicker morons. If there's one thing I have to agree with other Amerikkkans, it's the fact that most Eurolibs would immediately bend over and start sucking Uncle Sam's dick the moment communism starts winning (as you could see this moment) and their precious imperialist outposts 
and 
are in legitimate danger of losing
Just a rant. Anyways, have a good day comrades.
That's the thing, right? When people say "American culture", what they really mean is essentially "lowest-common-denominator American culture", which is itself a fancy way of saying "whatever the least marginalized Seppo jackass approves of that hasn't (yet) become global culture".
You absolutely could find hundreds or thousands of years of tradition, mythology, and landscape, as well as quality banter, within the borders of Seppoland, but you would just not find any of that labeled as "American" culture — you could even find culture in Seppoland that is new, yet also decidedly not plastic, but which would again not be labeled as "American" culture. Because the nationality generally pointed to by the term "American" is a colonial identity, anything that goes against colonization is not allowed, and would not allow itself, to be given that label. "American" culture has a prudish, puritan heart in a thick coat of cultural theft and bastardization and fabrication under capitalism, that must, like capitalism itself, continually expand through yet more theft and yet more plastic junk until it cannot sustain itself anymore.
The amount of things you could call "real" American culture that would remain if you took away all of the theft and junk, would be absolutely negligible, and would not fit together into anything cohesive and comprehensive; on top of this, Seppoland's cultural imperialism, and the inevitable march of technological progress, has left so many originally "American" things as part of essentially "world culture"; and on top of this still, a fair amount of the "real" American culture is just not particularly salvageable given the wretchedness of Seppoland in general.
All of this has honestly fucked with me as an Anglo-American born and raised and still living in Europe, because while I am treated as an immigrant's child, as I should be... The children of immigrants from other countries actually have those thousands of years of culture to fall back on for an identity, whereas I have fuck all. So I'm basically pushed by everyone around me to identify with a nationality without any real substance, like an ethnic null pointer error — and I've spent my life basically trying to figure out how exactly to make that work, for better and for worse. This is actually a big part of why I am so opposed to Seppoland's cultural imperialism, and admire your work a lot, albeit critically.
Edit: To be specific I think you are often poor on racial issues, that you tend to be opinionated and over-extrapolate from your own very limited perspective in a very unhelpful way. So it would do you a lot of good to be more inquisitive about racism in both Europe and Seppoland.
Edit 2: This thread has made me think considerably less of you and your potential for growth. Perhaps I should ask Hexbear to set up its own version of NoYank.
