Why would anyone be a Communist in 2024?
Invoking the Old Gods helps establish a new community, one with a particular moral sensibility.
Young people often invent new political ideologies to meet the new demands of the new era in which they find themselves living. And here is a younger person identifying with an old political brand. Instead of inventing a new political ideology, why would they instead try to revive an old ideology that is infamous for its failure? We never see this behavior with truly political movements, but we do often see this behavior with religious movements: people want to speak the Old Words and go through the Old Rituals in the hopes of gaining the favor of the Old Gods and thus, in the real world, they can become popular with the group of heretics who also worship the Old Gods.
This kind of movement, more religious than political, is less concerned with real world change and more concerned about establishing a community with a particular moral discipline, a community with its own strict understanding of what it means to be a member in good standing, a community with its own understanding of Halal - what things you can say, what you can eat, who is a hero, who is a villain, what clothes you can wear, etc. (Eat only organic food, avoid food full of insecticides, avoid clothing made with sweatshop labor, perhaps only buy old vintage clothing, to avoid giving money to the modern clothing industry, with all of its exploitation). This is a group working to establish its own strict sense of good and bad, and also, like any good religion, maintaining that particular understanding of good and bad in the face of daily life, with all of its tedium, and so maintaining the community, which is more important to them than any political result.
Of course, militant religious groups can become politically powerful, and perhaps this movement will become politically powerful, but such movements are always illiberal. Like any extreme religious movement, such a movement will not be comfortable with liberal democracy. Indeed, liberal democracy is the enemy of all such movements, as liberal democracy allows for the possibility that there is more than one understanding of good and evil. A revived Communism, functioning more as a religious movement than a political one, will insist that their understanding of good and evil is the only one that is true.
The communist ideal of a society full of cooperation and free of exploitation has always been a dream close to humanity’s heart, but flawed ideas need to be improved upon as new knowledge about human society becomes available.
