There is no question that there is no "Russian democracy". Putin is a dictator - just not one as powerful (inside his own country) as Kim or the Chinese ruling elite or Stalin/Brejnev/Hrusciov etc. For an example of this, there is public opposition to Putin in Russia (Navalny, Kasparov some years ago), and even though it is repressed (imprisoned, covertly poisoned), it is not brutally obliterated like it would be in, say, N Korea, or in Stalin's USSR.
And even in the worst dictatorships, mass public protests will almost always lead to the regime being toppled (perhaps only to be replaced by a worse regime, unfortunately, but still toppled). The population of any country is simply too huge to completely ignore, if it turns against the regime en masse.
If you don't believe any of this, then tell me - why do you think Russia is investing so much resources in internal propaganda? Why are they pretending to hold free elections? Why does Putin pretend he has a noble goal in Ukraine? It's certainly not fooling world leaders, so if his own population can't do anything about it, why even bother?
