I don't understand what's happening, could someone explain?
What is it that they are so passionate about that they start fighting?

Although it looks unbelievably unprofessional, there is something sort of nice about people who care enough about politics to to start a fight... assuming it is not so that they can line their own pockets some more.

Time to start that "Ukranian Politics and Orange Revolution" thread, I think!

Seems like a mix of Ukrainian and Russian in this video; is it expected that everyone can understand both languages?
