During the Spanish Inquisition scenes of season 4, several of the actors were obviously mixed-race Latinos and and a Lebanese-American man. This is not only historically wrong but a late 20th century-21st century generalization of Spanish-speaking peoples. During the Inquisition, the Spanish authorities held purity of European blood to such a precedence that anyone who was Jewish or Muslim was persecuted. Those accused of witchcraft were not the main victims of this form of ethnic cleansing. Due to the higher previlence of those from Latin America in the U.S., most Americans tend to forget that Spaniards are actually white Europeans.
The creaters of True Blood should have done more of their research before they created those scenes.
