You've clearly selected your data to match your existing understanding of the world.

You've selected one carefully curated statistic and used it to justify a sweeping generalization you already held about "Marxists".

You also are "lying by omission". Yes, autocratic governments that call themselves communist have killed a great many people in famines and political killings.

But so have many democratic governments and non communist autocratic governments. (To say nothing of the hundreds of millions of deaths at the hands of Capitalism.)

Look, we can disagree politically. But please at least do so honestly and in good faith.
