It's wrong to idealize violent groups
Bob talks about how awesome pirates to his buddy Pete.
Pete wants to give a disagreeing opinion.
Pete points out that pirates plundered towns and killed people.
Pete points out that the British Empire's many conquests in that same era were much cooler.
Bob concedes that's valid, but he still thinks pirates' stance on democracy and equal pay made them progressive for the era.
Bob counters by pointing out the British Empire's ships had grossly unequal pay and people forced to sail by threat of violence.
