“He who does not deliberately close his eyes cannot fail to see that the new “critical” trend in socialism is nothing more nor less than a new variety of opportunism. And if we judge people, not by the glittering uniforms they don or by the highsounding appellations they give themselves, but by their actions and by what they actually advocate, it will be clear that “freedom of criticism” means’ freedom for an opportunist trend in Social-Democracy, freedom to convert Social-Democracy into a democratic party of reform, freedom to introduce bourgeois ideas and bourgeois elements into socialism.”
