The difference are certainly minute compared to the possible variety of differences in the world. In Japan, for instance, varies ethnic groups live that either speak languages that are are as far removed form Japanese as Danish is from English, or genetically not related at all. To not even start about “Han Chinese”, which is an “ethnic classifier” that is so wide, it s more analogous with “Germanic”, “Slavic”, or “Romance” than it is with “Anglo-Saxon”; and contains a larger number of inhabitants than any of them respectively. “Anglo-Saxon” on a world perspective is really quite close together and comparable to “German” or “Francophone”.
