>>215599I don't focus as much on all the "are X white?" stuff that you get on /pol/, but as I understand it all whites can basically trace their roots back to the same Indo-Aryan or Indo-European or whatever the fuck it's called civilization, so Germanics, Nordics, Mediterraneans, Anglos, and maybe Slavs (not really sure about them) are all descended from the same basic group of ancestors, whereas Asians (the slant-eyed kind anyway) and Negroes are pretty much separate evolutionary branches. Most Islander peoples developed in isolation for so long they're pretty much their own separate thing too, Australian Abbos for example are literally so different from us that they're almost a completely different species.
More significant than ancient ancestry though, all whites are basically lumped together by all non-whites regardless of how we see ourselves. If you're just talking about the superficial aspects of a culture, then yes just about any group can adopt the culture of another group, and no one culture can really be said to be completely free of influence from any other culture in a world where global communication and travel is possible. However, every culture that adopts that of another usually absorbs it into its own in some way, and the original culture dominates. Modern Asian countries like Japan or S. Korea might appear superficially Western in many ways, but their version of our culture is very different from ours and has a distinctly Asian flavor to it. We absorb shit from them too, like anime and whatnot, but we Westernize it and create our own version of it. When the Germanic tribes invaded Rome and basically replaced the Roman empire, they absorbed aspects of Roman culture but it became a distinctly Germanic version of Roman culture, not strictly Roman. Romans did the same thing with Greek culture when they conquered them.
Some cultures coexist more easily than others, but in general people stick with their own kind and see people of other races as outsiders, even if they are on friendly terms. In particular, non-whites identify mostly with their own groups and see themselves as members of a culture distinct from "white" culture, even if they are pretty much Westernized to the point that there is little real cultural difference between them. Asians in America are a good example of this. By and large, Asians tend to assimilate well. They learn English, work in the same industries as white Americans, don't commit crimes or cause problems, and generally dress, speak and behave the same as Whites. However, if you get to know one, you will discover that they generally identify as Asian first and American second, and consider themselves part of a distinctly different group from Whites. Even a person of Japanese descent born and raised in America, who has more in common with his white friends than he would with someone in his own country, will usually identify as Japanese-American rather than simply American. An American black has almost nothing in common with an African, but blacks always identify as African.
So, in short, we're pretty much back to the old "CivNat" argument here: can racial groups get along, and if so can they form a nation based on cultural beliefs and values rather than on race? The answer to the first question is yes, but the second is mostly no. Mostly what you end up with in trying to do something like this is a situation like modern America, where everyone superficially pays lip service to the idea that we're all one nation, but identifies with their own ethnic subgroup nonetheless. Whites, be they Med, Anglo, Germanic, Nordic, Slav, whatever, will always be lumped into the same generic "White" category by Asians, blacks, etc. These non-white subgroups, even if they don't directly cause trouble, will still constantly undermine and take advantage of Whites. Thus, even though the overculture can basically function, it's not a nation in the true sense of the word, and it never will be. Even if race were just some kind of "social construct" or whatever the fuck, it still matters. People identify with their race more than the superficial aspects of the culture they belong to, and for whites to not do the same just works against us.
To put it simply: culture can transcend blood and different peoples can share a common culture, but ultimately blood, not culture, is what binds people together.
