he advances the theory that although the goals and aims of Communism are antithetical to human dignity and the rights of the individual
Of course they are. They have to be.
IIRC, Communism comes from “common” as in common good. Communism is collectivist - a person should do what’s best for the common good - represented by the State - even if its not best for themselves.
You cannot champion the rights of the individual while telling them they must act in the interest of the whole, even if that act is against their best interest. That is antithetical..
