Are you talking about “animal farm - a fair story” (loves the subtitle) by George Orwell ? A great read indeed, brings both brain food and entertainment.
Mostly became a vegan anarchist after reading it. It directly criticize revolutions and totalitarianism but the parallel with any regimes is logical. The roots of injustice is in power and control, which happens in any regime even the most democratic and liberal ones.
Not saying we should abandon laws and governments, but let’s not defend them in the sake of justice and fairness.
