TL;DR the link is about Ukrainians vs. Poles, not about Jews and/or Holocaust
Ukrainians and Poles were enthusiastically massacring each other for hundreds of years for various reasons (Catholics vs. Orthodox, serfs vs. land owners, nationalists vs. nationalists and so on). This part of history is accepted by both sides. It's true, that collateral damage included Jews sometimes. Some Eastern European Jewish historians describe it as "always choosing the wrong side". Jews were targeted for managing estates of Polish nobility, participation in establishment of Communist rule in Ukraine in 1920s, participation in establishment of Soviet rule in 1939-1941 in Western Ukraine. But they were never targeted for being Jews.
>During the first year of the German occupation, the OUN urged its members to join German police units. They were trained in the use of weapons so they could assist the German SS in the murder of approximately 200,000 Volhynian Jews.
This page has links to 18 separate massacres where people in Ukraine were killed specifically because they were jews. Stop spreading disinformation and engaging in holocaust denial. The famous Simon Weisanthal even survived one of the massacres.
>The most notorious massacre of Jews in Ukraine was at the Babi Yar ravine outside Kiev, where 33,771 Jews were killed in a single operation on 29–30 September 1941
>According to The Simon Wiesenthal Center (in January 2011) "Ukraine has, to the best of our knowledge, never conducted a single investigation of a local Nazi war criminal, let alone prosecuted a Holocaust perpetrator."
