Tindale comments that "the portrait painted of Darwinian ideology is a caricature, one not borne out by any objective survey of the works cited." The fact that similar misrepresentations of Darwinian thinking have been used to justify and approve racist practices is beside the point: the position that the legislation is attacking and dismissing is a straw man. In subsequent debate, this error was recognized, and the eventual bill omitted all mention of Darwin and Darwinist ideology. Darwin passionately opposed slavery and worked to intellectually confront the notions of "scientific racism" that were used to justify it.
