Delta: Participating in the transport of wildlife trophies is an abomination and a crime against nature and humanity and demonstrates an incredibly arrogant disrespect for the sensitivities of the human race in the current progressive global community. We demand the immediate cessation of this barbaric "sport". Stop transporting animal trophies now!
