You should seriously learn about Yanukovych before making any sort of claim regarding him. He was elected based on an enthusiastically pro-EU and pro-western programme, only to turn out to be a Russian puppet that not only enforced policies completely contrary to his programme but also pushed Ukraine into a dictatorship.
The "popular uprising" you glance over was actually months of demonstrations protesting Yanukovych unilateral rejection of the EU–Ukraine association agreement as ordered by Russia, which he campaigned and was elected for and contrary to Ukraine's parliament overwhelming approval.

You're talking about the same Yanukovych who felt compelled to exile in Russia.

Those who favour freedom under democracies are indeed partial against dictators who try to destroy democratic states and deny people's rights, specially if it to serve the interests of other totalitarian regimes.
But the US was far too eager to carry out regime change and so we have the dreadful situation today.
Let me see if Erdogan can be overthrown in the next elections in Turkey. No US involvement either.
If you live in a stable Western country, your trust in the next elections being fair and free is understandable, but in that case, refrain from any authoritative talk ("your arguments don't matter") about other places. In recent democracies that transitioned from totalitarian rule just a decade or two ago, elections are far easier to hijack than in the UK or Denmark.
"no-one would have batted an eye"
You cannot really make such a strong prediction about places like Ukraine, the Balkans, the Middle East etc. These are places where empires collide, and several crises in a century are almost a given.
Anyway I am fairly glad that Ukraine didn't end up like Belarus did, a satellite state of Moscow. Anything is better than becoming a satellite state of Moscow. Most of us from behind the Iron Curtain would rather fight a war than submit to Moscow again.
Interestingly, the Western leftists, who otherwise preach anti-colonialism from breakfast to sunset and then some, don't understand the same dynamic among white-majority nations. But it is still there.
Yes, he was. What you are leaving out is the fact that in spite of being elected based on an enthusiastically pro-EU platform, it turned out he was a Russian agent and betrayed his mandate to enforce Kremlin's anti-west agenda and force himself upon Ukraine as another kremlin-controlled dictatorship.
Except the people of Ukraine wanted none of that and protested against this betrayal, which culminated in the wannabe dictator seeking exile in Russia.
Somehow you leave this out when you talk about basic democratic principles. Why is that? Is it out of sheer ignorance?
What's also very odd is the way that you somehow try to portray anti-government protests as revolutions and regime changes, when this is a Hallmark of any democratic system: when a government doesn't follow through with their compromise and go directly against their mandate and people's will, they express their discontent and demand elections. How odd that when democracies reject Russia's interference, this is deemed as an anti-democratic coup.
