That is a look at Luther through a rose colored magnifying glass. St. Thomas Aquinas introduced the Europe to the concept of justice, positive rights and the natural law in his Summa Theologiae Secunda Secundae, hundreds of years before Luther was even born.
As for Luther's contributions to individual rights one need only review his condemnation of the peasants involved in the Peasant's Wars.
Peace be with you
I think that Luther really started to condemn the Peasant’s Revolt following the Weinsberg Massacre, when the Duke of Helfenstein and ~70 other nobles were forced to run the gauntlet of pikes. Do you condemn that as well?
