Very few people truly choose their government
And Ukraine is the best example. They chose the government before the Euromaidan and when they were fed up with it, they organized the revolt and replaced the elected government with those whom they supported and nationalists were among leading powers there and they are still there.
you can tell us what they've done to promote positive reconciliation and forgiveness in this matter
I'm not aligned with Młodzież Wszechpolska but I think the Catholic spirit they promote may be a key to bring closer Poland and Ukraine and help Ukraine to integrate in Europe. And in the neighboring thread about Poland and Ukrainian migrants I recognized a letter I saw before,
https://polishforums.com/news/poland-accepted-million-ukrainian-81149/2/#msg1601931, and I think the attempts to make Ukraine a Catholic country are already made and that's good for many reasons.
Ukraine, being mostly orthodox country, represents a big danger to Europe and Poland because we are completely different and Ukraine can't live and exist according to our mentality and values no matter what Ukrainians or their government says. Their only goal is to be accepted in Europe at any cost. The key word is accepted, not integrated. It means they will spread in Europe promoting their faith, their way of life and for Europe, which is too tolerant, it means extinction because Ukraine and Muslim migrants will replace Catholics.
Ukraine is too proud to admit its crimes against Poles and that's also can be described by their orthodox faith. Catholics can forgive and Ukraine is not about that. They say we need a dialog and that's possible only when they officially apologize and admit their crimes, but we know they won't ever do that until they accept Catholicism.
