Kudos to you for making such a generalization of W. Ukraine.
Not a generalization. I've spent considerable time working there. There is daily evidence of such behavior. Heck, they even named a street in honor of a Chechen terrorist - why, you might ask? Because he killed Russians. Jewish cemetaries vandalized. People with dark complexion stabbed. Ethnic Russian children beaten in school. All happened in just one week last October in Lvov.
