Why do some people oversimplify European genetics?

[Bobby Martnen]

I've seen some people saying that there is only NE and SW Euro admixture, and that NW Euro and SE Euro blood isn't real.

But this is a fallacy, and Europe can't be modeled on just a NE-SW Euro cline.

Northwestern Europeans have their own bloodlines, and even their own haplogroups.

You can divide the European race even more than 4 ways if you want, you can even divide them and include bordering non-European populations. You can do this with every race.

To answer your question though, I am not so sure but they have their motives.
