 More recently, scholars have criticized the theory as potentially racist in nature in its implication of one given ethnicity or culture supposedly being less fit for or less worthy of being qualified as "civilized", the built-in implication of which in turn would denote stereotypically "white" behavior as an objective norm for all societies to follow.The hypothesis was reconsidered recently by Barry Latzer, who suggested that black Americans had inherited a subculture of violence from white Southern American honor culture (who themselves had developed that culture from the brutal and lawless border region of northern Britain) and that difference in crime rates could be partially explained by this contemporary manifestation of Southern honor culture.Latzer's argument was criticized by German Lopez for not adequately demonstrating the alleged causality between culture and crime, and for not accounting for the decrease in crime rates in the 20th century or clearly defining the limits of what would constitute "culture" for the purposes of Latzer's argument.
