Currently the right-wing narrative is much more focused on the pride month and rainbow parades at the moment, but I wouldn't be surprised if the alleged white genocide is part of it. They are, basically, integrating everything they can find to oppose the system into their narrative - COVID-19 conspiracy theories, Russophilia, anti-vax positions and the culture war. Genocide against white people largely ignored by the woke mainstream media is too tempting to not make use of. In that way all right-wing reactionary movements are peas of a pod, whether they're led by Trump, Wilders, Kickl, Le Pen or Orban.
The only odd one out is KaczyĆski insofar as you can't really say that being pro Russia is part of his party's stance. He's still helping Russia indirectly though, as everyone who opposes a more unified European Union does. This is just the state of the world today, Ned Stark had it right: "The lone wolf dies, but the pack survives."
At least people are finally seeing that the USA aren't our allies, let alone friends. Baby steps.
