This is basically me thinking as I write, so take it for what it is.
As many things in politics I think we should see it in a sort of dialectical way. With a form of very liberal and globalist ideology dominating in west, the ideology in east have developed as an anti thesis to this.
I think there are two good explanations for this. One is that the existing structures of power largely remained from the communist era. The same people, but promoting a different ideology. And just like they had learned to follow Moscow, they now looked at Washington and Brussels. Therefore, a populist uprising to get rid of these people is perhaps not that surprising.
Secondly, the citizens in east are less naive and idealistic in issues such as migration which became a huge clash long before people started talking about gay rights and so on. This is also an actual material issue, that direcly effects normal peoples every day life, which I think makes it more important than the stance on "lgbtq-rights", which is more symbolical. Rather a sort of signalling about what camp you belong to, with the two extremes in either end are just ridicilus.
But the way dialectics work is usually the thesis and anti thesis ending up in a synthesis which is where I think Europe will be heading soon. We can see the change all over west, with globalism essentially being completly abandoned for a more realistic view on the nation state and the need for a united Europe to stand up against global capital and other super powers, rather than just being geography in a multicultural world with open borders.
Also, the wests naive stance on migration is more or less gone. The swedish Social Democrat is just about to change leader, and the first thing she said in her speech was that the most important issue for Sweden to deal with is the violent and gang-related crime, mostly by second generation migrants with parents who have not become a part of Sweden, and that she will do everything it takes to fight this. Which shouldnt be controversial, but is a huge discursive change since the party until now only talked about it as a result of socio-economic problems.
I mention this, because I think Sweden is probably the last (perhaps except Germany) country with the main parties both left and right recognizing that migration have caused huge problems for Europe.
This, in combination with a more nationalist (and eurocentric) approach rather than a globalist are certainly signs that west is getting closer to the east in a lot of important issues. And I think this is positive in combating the other extreme positions, where ethnicity starts to get into the picture, and it is possible to shape a sort of pan-european discourse about the importance of national identity, but that ethnicity doesnt need to be a part of it.
And I see this as the springing point, people all over Europe are happy and proud to be europeans, and want to cooperate with eachother. But they identify even stronger as hungarian, dutch, finnish and so on, and want as much national soveirgnity as possible.
