Those same "Maoists" would have denounced Mao himself for the idea of New Democracy and the policies he adopted toward the national bourgeoisie. What all ultras have in common is that they refuse to take real material conditions into account, and this results in their inability to conceive of any sort of tactical flexibility as anything other than "betrayal", a straying from the purity of the dogma. They live in a world where reality and the constraints it imposes are irrelevant and all that matters is having the perfect ideas; in short they are idealists.
