Also, not every Trigan/Vorg was shown as a shining white (no pun intended) example, for example Yenni, the Trigan in the story that introduced the Hericons. At the same time the Hericons who were also 'non white' seem to be a fusion of the Byzantine and Persian empires and are shown to be very advanced technologically and culturally. The Gorths are meant to be in my mind representative of any 'barbarian horde' throughout history.
I take a bit of issue with this, for one thing I am tired of the PC culture that is popping up everywhere, but to say that every non-white is a racial stereotype is extreme.
As with many 1960s pulp stories, it features one or two capable women to serve as foils and romantic interests for the male heroes" Women are generally depicted as weak and emotional, but this aspect of the comic is at least more progressive than the racial aspects. Alien stand-ins for Asians and Africans are depicted with extreme stereotypes and condescending attitudes that would generally be considered very distasteful today. "The comic's writing and artwork reflect its 1960s boy's magazine origin in the depiction of non-white races and women. 2 Fair use rationale for Image:Trigan2.jpg.
