It's so ute how a Russian nationalist speaks of "Ukrainian nationalism" in such pejorative terms, like you're entitled to a national identity (even though you've yet to form one) while the parent nation you sprang from is not.
By the way, if this is the "origin" of Ukrainian nationalism, then how does it predate his birth? Czar Nicolas I bitched about "Ukrainian Nationalism" throughout his entire misbegotten reign. When he finally had the good grace to die, Bandera wasn't born yet.
Borrow a history book from someone who lives in a country where books are still legal, and be someone literate to read it to you.
