That’s called “confirmation bias” based on 250 years of lies.
LOL 250 years of lies! Katyn, the deportations from Poland, Latvia, Lithuania and Estonia, the rapes and looting of Germany, the Holodomor, the massacres of Ukrainian Catholics and deportations in the 19th century, seizure of the Warsaw public library and carting of its contents off the St. Petersburg after the final partition of Poland, all lies!
You no doubt notice he failed to mention the Massacres in Volhynia and Galicia in his reply to you.
