These are not arguments supporting the validity of forced theft - communism.

The way of the leftist discussion.... try to get off the subject as fast as possible, as logic demands an acceptance that their own logic requires admitting to the approval of applying force and control over other people.

It says far more about the head space of the individual who is arguing for authoritarianism, than the argument itself.
The communist dogma has no basis in logic.(with the proviso of very small communities working together - for they work brilliantly)

It cannot scale up without bureaucracy, and with the bureaucratic layers, comes corruption, nepotism, and inefficiencies.

Reality is a bugger for the left.
