The post of my that you initially responded to had to do about how similar Europeans are to each other. Why are you bringing opinions into the matter? Please use facts and and please provide sources.
It is a fact, not an opinion, that the PCA plots by Davidski, who maintains the Eurogenes site and has Polish ancestry, and Dr. Doug McDonald show Polish to be close to Belarusians, Sweden, Norwegians, and Finns.
They also show Germans to be close to the French and Hungarian. That is a fact and not an opinion.
This proves that Europeans are very similar to each other when put on a PCA of world populations. The presentation by Dr. Michael Hammer and results of the program called ADMIXTURE (the program's name is all caps) prove that European populations are more similar to each than other world populations. Yes, there are some differences between specific populations but the similarities cause all of the DNA companies to provide results that have north European people looking for an Iberian ancestor or a Latin American thinking that they have a recent ancestor from northern Europe. Why is this point not understood by you?
The following is a PCA plot by Dr. Doug McDonald -
