Let's compare and contrast shall we?
The Maidan took over the justice building in protest of orwellian anti protest laws and left when they changed. Bad, arguably I suppose, not unheard of in a mass protest movement of millions.
The Donbass separatists took over just after Russia seized Crimea, and took over all the centers of government and declared the whole town to be independent. They just so happened to do it with Russian supplied arms and with the aid of Russian troops coming up from Crimea.
And if you think that Maiden is what a violent overthrow looks like, you're high. Get help.
The violent overthrow that ended outside of the actual hall of government without a breach. And Yanukovich ran to Russia rather than face criminal prosecution that was likely incoming, His entire administration collapsed and he left the country sans not only a president, but any administration.
So the Rada voted his ass out, with a vast majority. Not a coup. Not a violent overthrow. But you know that.
