Stick to physics. Russian speaking doesn't = feeling Russian. All the people in Izyum and Kupiansk who embraced Ukrainian troops s liberators were Russian speaking. Your swallowing this Russian useful idiot mythology shows how simplistic and ignorant of Ukrainian history and sociolinguistics you are. Read Voline's history of the anarchist Makhnovist movement in 1918-1921 and about how Shevchenko defined Ukrainian identity in civic nationalist terms to understand the territory. Your thesis is historically illiterate. I'll make a deal with you: if you stay out of history and geopolitics, I'll stay out of physics.
