Paulina are they mistaking here then?
I don't know. Did they explain why it's incorrect? It would have to be explained to me in a relatively simple, non-scientific language ;)
And if it's incorrect then why Poland, Ukraine, Belarus, Russia, Slovakia, etc. have such a high percentage of R1a? Doesn't this mean those nations are related to each other?
Serbia is part of Europe. Inclining to the right exists in Serbia too. You are mixing political with geographical concepts.
I don't understand...
As far as I've noticed even this forum is clearly showing polarization between two wider groups , those who feel closer to Germans (pragmatic ones), and the other group,
True, but Pan-Slavism movement wasn't very popular in Poland and isn't popular to this day.
aware of their origins (Slavic in historical, not biological sense).
And what does mean "Slavic in historical sense"?
Pan Slavic ideas exist to a certain degree everywhere Slavic people live.
True, but in Poland it isn't a big degree, I would say quite small, it's much bigger in Russia, and apparently in Serbia.
As I wrote before, Pan-Slavism wasn't very popular in Poland. The reason for this was the fact that it was used as a political tool by both the Russian Empire and the Soviet Union to dominate and govern other Slavic nations:
"Pan-Slavism in Poland
Although early Pan-Slavism had found interest among some Poles, it soon lost its appeal as the movement became dominated by Russia, and while Russian Pan-Slavists spoke of liberation of other Slavs through Russian actions, parts of Poland had been ruled by the Russian Empire since the Partitions of Poland. Historically, Poland often saw itself in partnership with non-Slavic nations most of the time, such as Hungary, or Lithuania under the Polish-Lithuanian Commonwealth from 1569 to 1795. The influence of 19th century Pan-Slavism had little impact in Poland except for creating sympathy towards the other oppressed Slavic nations to regaining independence. At the same time while Pan-Slavism worked against Austro-Hungary with South Slavs, Poles enjoyed a wide autonomy within the state and assumed a loyalist position as they were able to develop their national culture and preserve Polish language, something under threat in both German and Russian Empires. A Pan-Slavic federation was proposed, but on the condition that the Russian Empire would be excluded from such an entity. After Poland regained its independence (from Germany, Austria and Russia) in 1918 no major or minor force considered Pan-Slavism as a serious alternative, viewing Pan-Slavism as little more than a code word for Russification. During Poland's communist era the USSR used Pan-Slavism as propaganda tool to justify its control over the country. The issue of the Pan-Slavism was not part of the mainstream political agenda, and is widely seen as an ideology of Russian imperialism."
