This, honestly, is the worst line of argumentation that I repeatedly hear.

Okay, so Communism, by definition, has to be stateless, classless, and moneyless.

What happens when there's people that don't want to play along? Because, good luck convincing 100% of society that we should forgo private property rights as currently understood. Well, there has to be some entity that has the authority, by means of the threat of force, to make people comply. However you want to slice it, that entity amounts to a de facto state. And, as seen played out throughout history, it's likely authoritarian in nature.

When the above plays out, the next generation of ever-naive Communists can point to it and say "B-b-but it's not real Communism!"

The conditions of classless and moneyless aren't even worth seriously entertaining. There's a reason 100% of the time whenever a new society has emerged from scratch, some form of class hierarchy and some form of currency have always organically emerged. The complexity required to sustain increasing societal growth and technological development without those would be unfeasible.

You're falling for their very lies and deceit. That's how they've tricked so many Americans into accepting this socialist/communist bs. Every single attempted implementation of Communism has resulted in mass murder/starvation/loss of freedoms/economic crashes etc.

To be so foolish as to keep falling for these same lies over and over and over and over again is to essentially sympathize with and support our enemies. (We are at war)

I implore you to read the Constitution, the Declaration, the writings of Thomas Paine and other founding fathers, for if you accept Communism as something to be wanted, you are lost and antithetical to what this nation and the American people stand for.

and why do you think that has happened every single time?
