The German sociologist Iris Wigger wrote that Morel's "Black Horror on the Rhine" campaign has caused much embarrassment to Morel's admirers today, who would rather remember the man who campaigned against the Congo Free State, but in fact, both campaigns were manifestations of the same racism since he believed that all black people were innately stupid and inferior to white people in all respects. Through Morel had been very forceful in condemning the cruel exploitation of the Congo Free State, Morel believed in a liberal imperialism, just not the cruel exploitative imperialism of the Congo Company. He wrote that it was the duty of whites to serve as the "trustees" for blacks and the "great white father" who would protect the "basic human rights" of Africans while at the same time accepting the "infantile" nature of black people, who not the equal in any way of whites. Morel himself did not see his campaign as racist and always presented himself as a friend to black people. In France, the French socialist Charles Gide wrote about Morel's claims to be a protector of Africans: "le genre de protection de M. Morel rappelle un peu le precepte que fait afficher la Society protectrice des animaux: 'Soyez bons pour les betes (Mr. Morel's kind of protection remind a bit of the precepts of the Society for the Protection of Animals: 'Be good to the animals').
