While I agree, I'd also say- all those I mentioned above (people desiring their own sovereignty, security, their own resources and the fruits of their labor, those desiring equality, and those who just so happen to be indigenous) also are existential enemies to the existing liberal order as well; the "liberal order" is maintained through stolen land, exploited labor, and rivers of blood, and all those seeking to end any of the above are inherent enemies.

This is the end result of genocidal, hegemonic, thieving and arrogant liberalism; the very nature of human dignity, and the desire for it from the exploited masses stands against them. There's not a single enemy out there that they did not create the conditions for, through their barbarism; communists included of course, as it is their oppression of the proletariat across the globe, and beyond that their imperialism (the highest form of capitalism, of course) that has created such conditions that were responsible for every communist uprising, and every creation of every AES state out there.

If you ask me, "humanity" is an existential enemy to the liberal order; all those with decency, and all those who desire decency, are their enemies, whether they have recognized it yet or not. They have made enemies of everything and everyone, save for themselves and their collaborators; and at this point I think it can be said that they (the liberals) are even the enemy of the human species altogether, as they work to plunge the world yet again into a world war (and this time, a nuclear armageddon), as they rapidly destroy the planet's ecosystem, and as they proliferate all of the most dangerous ideologies (fascism, religious extremism, tribalism, etc) and play with all sorts of horrific WMDs (and are quite possibly the cause for cv19, AIDS, etc).
