"Marxism" Or; "Communism" Is An Established Economic Doctrine.

It has a defined set of criteria which must be met. Rather like a computer algorithm.

Similarly; "Keynesianism" and; "Boisguilbertism" are established Economic doctrines.

Turns out; "Heterodox" is just a needlessly pretentious way of saying; "Unorthodox."

As in; "Opposite of Orthodox." As opposed to; "Same as Orthodox."

Not that I know a thing about it, It's all Greek to me(!)
