The government in Kiev not lifting a finger to keep those who do love the Nazis from using violence is the issue, not whether or not the Nazi lovers are the majority. The Kiev Kiddiels relied heavily on the Nazi boys when they were using a mob to overthrow the government so who believes they'll start to crack down on them?
I know that the only folks from Ukraine I know and talk with others in Ukraine through them say that support for the neoNazis is about fifteen percent of the population and another five percent or so sympathize with large parts of their agenda. They live near Kiev so how that differs nationally I don't know.
I also know that on a couple of video clips I watched there were men wearing the same armband as the Nazi groups wore during the mob violence in Kiev. That's just fine with you, right? Arm the Right Sector types and tell them to get those evil, "ethinc Russian terrorists"?
I work with a Jewish female who was originally from Odessa. She is still in touch with her family and friends there. She says that the Nazis in Ukraine thing is a bunch of exaggerated Putin propaganda.
Your percentages are greatly exaggerated.
