I am curious to know why Banksy does not go to Donetsk or Lugansk to see the destruction of civilians homes? I feel sad for the Ukrainian people whose homes have been destroyed by the current war. But we shouldn't forget the many civilians, who identify as Russian, whose lives have been destroyed by this war in the Donetsk and Lugansk.
P.s. you mention non existent Nazis in Ukraine. Let us be honest about this. There are many neo Nazi military formations in the Ukrainian army, the Azov regiment being the most famous. Across Ukraine Stepan Bandera, who collaborated with the genocidal activities of the German Wehrmacht during World War 2, is widely celebrated throughout parts of Ukraine as a national hero. There are hundreds of streets across Ukraine named after him and the other leaders of Ukrainian fascism. Large numbers of Ukrainians are rightly horrified by what Bandera and his henchmen got up to but sadly there are substantial numbers of people in Ukraine who still celebrate this genocidal Nazi.
