Original sentence: "  This outburst made clear that even the supposedly gentler characters were thoroughly tainted by racism and the fear of miscegenation.Every reference to this relationship is visual.In terms of the dramatic action of the film, it is by far the strongest initiator of behavior on the lead character's part.Perhaps significantly, Ethan, despite his hatred of the Comanches, appears to be very learned in their language and culture.The most startling part of this plot undercurrent is that there is not one word of dialog alluding to the relationship and feelings between Ethan and Martha, despite the importance of those factors to the plot.Thus he is driven far more by an obsessive need for vengeance than pure unmotivated racism
Edited sentence: "  This outburst made clear that such views were simply accepted, and are perhaps even acceptable.By showing the Comanches as being just as bad as Ethan, if not worse, the film presents a somewhat equivocal defense of manifest destiny.Some critics even go so far as to say that this drives Ethan’s hunt for the Comanches, rather than the obvious goals of rescuing Debbie and avenging his family.The only references within the film to such a relationship are a few highly ambiguous shots
