"The most democratic bourgeois republic is no more than a machine for the suppression of the working class by the bourgeoisie, for the suppression of the working people by a handful of capitalists."
This doesn't seem consistent with what the AWL usually says about bourgeois democracy. And it shouldn't be. Because the "no more than" part is simply false.
And in any event it was hypocritical for Lenin to write like this because the Soviet Union of 1919 was hardly a workers' democracy, a "state of the Paris Commune type." One could argue that under the circumstances it simply couldn't be anything other than an "authoritarian workers' state," but Lenin never acknowledged this.
