Not at all sure about that. Communist states require almost nothing from its people other than a willingness to absorb pain meted out by a top heavy and corrupt centralized government that literally does all the citizenry's thinking for it. The running joke about the Soviet Union for decades was that all the government had to do was make sure the masses got their vodka even if they had to stand in line for it and it was all good. Communism simply requires a willingness to roll over. Oddly enough Communism is only the second worst form of governance ever invented....Royalty being the worst. Not at all a surprise that the two worst are frighteningly similar in some ways.
Fascism requires that the citizenry maintain a manic fervor, commanded to it by the Fascist. It can usually be exhausting as is Trumpism. Trump is utterly compelled to roil his base constantly for example. While followers tend to be compliant, ultimately unless the big payoff the Fascist has been promising is realized fairly quickly in relative terms there is just so many times you can trip their power buttons to ever higher levels of tweaked before they just run out of gas. Least we forget, Mussolini and his mistress ended up hung by their heels in the square, her skirts around her neck, a rather undignified position you would expect they did not anticipate.
Liberal democracy including our Constitutional Republic without question requires the most of its citizens. It requires a citizenry that understands its government and remains vigilant and engaged from between the ears, not from the gonads. At present our citizenry is neither cognizant enough about how its government is designed to work, assigning to it all sorts of nonsense both from the Left and the Right and our participation in it as citizens is much too much about gonads with much to little engagement from between our ears.
In addition, we have not been vigilant enough about the dangers of adopting technologies without understanding there socio-economic implications. Rampant access to broadcast media in the form of 1,000 channels and the Internet have served to drive wedges even deeper as the immediacy and constancy of their presence is something for which we were and still are totally unprepared. We have chosen to accept as knowledge or information or news material that is at best entertainment, at worst propaganda (entertainment with an intent).
At any rate, without question, Communism requires the least of the citizenry really only requiring the citizen to suffer silently, something human beings are particularly good at doing. Fascism requires that the citizen maintain manic levels of fervor, certainly more difficult that suffering silently. Liberal Democracy requires real citizen participation and understanding of its government processes else it slips away most likely to less free forms like quasi-Royalty or Fascism.
