This video was posted to counter the Russian claim that Ukraine's uprising was the product of 'radical extremists'.
It's clear that Svoboda was active in the protests. But as you can see in this video, it's equally clear that far more ordinary Ukrainians who would be going about their business if the government was doing its job were actively protesting, too.
In February, the Christian Science Monitor described protesters this way:
Those demonstrators were a diverse mix of radical groups, self-defense units, retirees, entrepreneurs, and students, united in their call for President Yanukovych's resignation, if increasingly disappointed about the lack of progress during the past three months. Even as the police and crowds of protesters clashed on Wednesday morning, women passed out sandwiches, milk, and water from a safe distance, while others used hammers and pick axes to chip away concrete bricks from the square’s sidewalks, which lay in scattered stockpiles away from the front line.
“So, do we look like terrorists or extremists?” joked Katya Federenko, a recent college graduate who was helping pile stones on Independence Square, or the Maidan.
I'll let you decide the answer to that question.
