Well, some guy in Washington used some official soviet demographics to draw the conclusion that "millions had been killed", because the population wasn't as high as it was "supposed to be".
By the same logics we can find that all western industrialized countries have mass murdered their own populations, because families contain less children. Not 6-10 as was the case pre-industrialization. With better health care and better standards of living in general, the risk for losing children is lower and thus fewer children are born. Fewer births is what to be expected for the USSR in that period, as with all countries in the same situation, because of industrialization.
The same official statistics show at most a couple of million casualties due to famine - due to kulak scorched earth tactics in response to democratization/collectivization. In the early USSR much land was privately owned. After the revolution land was given away to those who plowed it. However, after a couple of years land accumulated into the hands of a few. It's a natural mechanism. It's enough that some peasant gets sick or otherwise unlucky so that he is forced to sell his land for some immediate money. The kulaks emerged as a class with leverage on the rest of society.
As long as the population is increasing, but perhaps less and less, things should be ok. And the population of the USSR increased dramatically during its existence. Now, the republics struggle with both economy and their population numbers. Take a look at EU countries like Latvia even. No "mass murder", but surely people live worse and in Russia not as long as before. Taking away social security, healtchare and education is a type of violence. And for that you, liberals, are responsible.
And what about the far right violence in Ukraine?
This is how godless opposition is treated (in areas where they haven't banned the opposition parties - Russian TV is already banned) “Comrades, I’m Rostislav Stepanovich Vasilko, First Secretary of the KPU Gorkom in Lvov; the Banderovtsy beat me up badly in Kiev. They stalk my mom; they put out death threats against my children. They threatened to kill my common-law wife and me. Help me to find political asylum in another country. On 22 February, from 11.00 to 23.00, Euromaidan ruffians tortured me in Mariinsky Park; they drove needles under my fingernails and beat me with clubs and fists. They punctured my right lung; they broke three ribs, my nasal septum, and a facial cyst. They cracked my skull and I have a second-degree concussion. I got bruises all over me. Tomorrow, the doctors will do a spinal tap. I’m in the deep doo-doo! The Banderovtsy cleaned me out! They took my documents, my money, and my cross on a gold chain”

How can you have free elections and an election campaign when fascists patrol the streets, make people vote at gun point, when opposition HQs are occupied, parties and TV-channels banned?
The best democracy money can buy.
The problem with Stalin was that he was too kind. In reality it was one of the most properous and successful eras in history. Growth has never been that high before or after. They literally started in the mud and ended in space. Socialism, and the planned rational economy, was and is a major threat to the past and current rulers, which is why they have to demonize and combat it by all means. It has nothing to do with "freedom" or "democracy" (of which there is none).
