Bandera remains a highly controversial figure in Ukraine.[9] Many Ukrainians hail him as an example,[10][11] or as a martyred liberation fighter,[12] while other Ukrainians, particularly in the south and east, condemn him as a fascist,[13] or Nazi collaborator,[10] whose followers, called Banderites, were responsible for massacres of Polish and Jewish civilians during World War II.[14][15]

I see you've already been corrected by someone who explained you who Stepan Bandera was. I don't blame you for not digging deeper than the wikipedia article of the song, but I encourage you not to antagonize people with concerns about Nazism and strong opinions about it on the internet.

As for why the Wikipedia article of a song to Stepan Bandera doesn't start with a warning about him being Nazi (or have a "Criticism" section at the very least), I hope that also makes you reflect on the bias in Wikipedia when discussing topics with geopolitical implications.

Stepan Bandera is a well known figure that has been discussed heavily since the beginning of the war, and his rehabilitation as a "Ukrainian patriot" completely whitewashing Nazism is extremely concerning to socialists like me, and even to non-socialists in neighboring countries like Poland.
